Research suggests Ukraine has significant REE deposits, mainly in Donetsk, Luhansk, and Poltava, with control split due to conflict.
It seems likely that Russia controls about 40% of Ukraine’s metal resources, including REE, in occupied regions like eastern Donetsk and Luhansk.
The evidence leans toward Ukraine retaining about 60% of REE, especially in regions like Poltava and Dnipropetrovsk.
Controversy exists over exact resource values and control, given ongoing conflict and classified data.
Resource Distribution and Control
Ukraine’s natural resources, particularly Rare Earth Elements (REE), are distributed across several regions, with significant deposits in the east and center. Key regions include Donetsk, Luhansk, Zaporizhzhia, Dnipropetrovsk, Kirovohrad, Poltava, Vinnytsia, Zhytomyr, and Kharkiv. Due to the conflict, Russia controls parts of Donetsk, Luhansk, and Zaporizhzhia, estimated at about 40% of Ukraine’s metal resources, including REE. Ukraine maintains control over the majority of its western and central regions, likely holding around 60% of REE resources.
Specific REE Deposits
Notable REE deposits include the Shevchenko Field in Donetsk (under Russian control) and the Novopoltavske deposit in Poltava (under Ukrainian control), with others spread across regions like Dnipropetrovsk and Kirovohrad, all under Ukrainian governance.
Economic and Geopolitical Context
The division of control impacts Ukraine’s economic recovery and global supply chain roles, with both nations leveraging these resources strategically. The U.S. and EU show interest in Ukraine’s minerals to reduce reliance on China, with recent talks aiming for joint development.
Survey Note: Comprehensive Analysis of Ukraine’s Resources by Region, Focusing on REE
Ukraine stands as one of Europe’s most resource-rich nations, with an estimated $15 trillion worth of mineral resources, including Rare Earth Elements (REE), which are critical for high-tech, renewable energy, and defense industries. This analysis, conducted as of April 28, 2025, provides a detailed examination of Ukraine’s resource distribution by region, with a focus on REE, and assesses control by Ukraine and Russia in the context of ongoing geopolitical tensions.
Overview of Ukraine’s Natural Resources
Ukraine holds approximately 5% of the world’s mineral resources, encompassing 23 of the 50 materials deemed critical by the U.S. government. Beyond REE, key resources include iron ore, coal, natural gas, manganese, titanium, lithium, and uranium. The country’s geological diversity, spanning from the Ukrainian Shield to the Carpathians, supports this wealth, but the ongoing conflict with Russia has disrupted access and control, particularly in eastern regions.
Distribution of Rare Earth Elements (REE) by Region
REE deposits are found across multiple regions, often as coproducts in phosphate, titanium, and other ores. Based on data from the Ukrainian Geologic Survey (Ukrainian Geologic Survey Investment Opportunities), the following regions are significant for REE:
Region
REE Deposits and Notes
Control Status
Donetsk
- Shevchenko Field of Lithium Ores (major lithium deposit, part of REE)
- East: Russia (including Shevchenko Field)
- West: Ukraine
Luhansk
- Significant REE deposits, part of broader mineral wealth, exact locations unspecified
- Mostly Russia
- Some west: Ukraine
Zaporizhzhia
- REE deposits as part of broader mineral resources, specific sites not detailed
- South: Russia
- North: Ukraine
Dnipropetrovsk
- REE deposits, part of broader mineral resources, less developed compared to east
- Fully Ukraine
Kirovohrad
- REE deposits, part of broader mineral resources, nickel and cobalt also present
- Fully Ukraine
Poltava
- Novopoltavske deposit (phosphate ores with REE coproducts, one of the largest globally)
- Fully Ukraine
Vinnytsia
- REE deposits, part of broader mineral resources, less detailed
- Fully Ukraine
Zhytomyr
- REE deposits, part of broader mineral resources, less detailed
- Fully Ukraine
Kharkiv
- REE deposits, part of broader mineral resources, some areas near Russia under dispute
- Mostly Ukraine
- Some east: Russia
The Novopoltavske deposit in Poltava is particularly notable, with proven reserves of phosphate ores containing REE coproducts, and it is fully under Ukrainian control, with exploration and production licenses open for nomination (Ukrainian Geologic Survey Open Bids). Conversely, the Shevchenko Field in Donetsk, a major lithium deposit with REE potential, is located in the eastern part under Russian control, as per reports from Al Jazeera (Mapping Ukraine’s Rare Earth and Critical Minerals).
Control of REE Resources
The ongoing conflict has led to a significant division of control over Ukraine’s mineral resources. Russia occupies approximately 20% of Ukraine’s territory, including large parts of Luhansk, Donetsk, and Zaporizhzhia, which, according to estimates by Ukrainian think tanks We Build Ukraine and the National Institute of Strategic Studies (via Reuters, as reported by Al Jazeera), account for about 40% of Ukraine’s total metal resources. Given that REE are part of these metal resources, it is reasonable to estimate that Russia controls around 40% of Ukraine’s REE, primarily in the occupied eastern regions.
Ukraine, on the other hand, retains control over the majority of its western and central regions, including Poltava, Dnipropetrovsk, Kirovohrad, Vinnytsia, Zhytomyr, and most of Kharkiv. These regions likely hold approximately 60% of Ukraine’s REE resources, with key deposits like Novopoltavske being actively managed and open for investment. However, exact reserve figures for REE are often classified, as noted for lithium, titanium, and uranium in reports from Visual Capitalist (Mapped: Ukraine’s Mineral Resources), adding complexity to precise quantification.
Broader Resource Distribution by Region
Beyond REE, Ukraine’s resource wealth includes:
Donetsk and Luhansk: Rich in iron ore, coal, manganese, and titanium, with significant portions under Russian control, impacting Ukraine’s industrial base.
Zaporizhzhia: Contains iron ore, manganese, and natural gas, with southern parts under Russian control.
Dnipropetrovsk and Kirovohrad: Key for nickel, cobalt, and uranium, fully under Ukrainian control, supporting mining operations.
Poltava: Beyond REE, rich in iron ore and manganese, fully Ukrainian-controlled.
Other Regions: Vinnytsia, Zhytomyr, and Kharkiv have lesser mineral deposits but are strategically important for Ukraine’s resource base, mostly under Ukrainian control.
Regions like Crimea, annexed by Russia in 2014, and parts of Kherson under Russian control, are not major REE regions but contain natural gas and other minerals, further complicating resource access.
Economic and Geopolitical Implications
The division of control over REE and other resources has profound implications. For Ukraine, retaining control over regions like Poltava and Dnipropetrovsk is crucial for economic recovery, with the government seeking international investment to develop deposits like Novopoltavske. Recent discussions with the U.S., as outlined in a framework agreement reported by Reuters (Mapping Ukraine’s Mineral Deal with the US), aim to jointly develop Ukraine’s REE and critical minerals, potentially creating a Reconstruction Investment Fund to reinvest revenues into infrastructure.
For Russia, controlling eastern regions like Donetsk and Luhansk provides access to significant mineral wealth, enhancing its strategic position in global markets and denying Ukraine revenue. This control adds a “strategic and economic dimension” to the conflict, as noted by Dr. Robert Muggah of SecDev, reported by BBC (What Minerals Does Ukraine Have and What Are They Used For?), with Russia seizing resources worth an estimated $350 billion in occupied territories.
Globally, the U.S. and EU are keen to reduce dependence on China for REE, with Ukraine’s potential highlighted in reports from the World Economic Forum (The Future of Critical Raw Materials in Ukraine and the World). This interest underscores the geopolitical stakes, with Ukraine’s resources seen as vital for Europe’s green transition and post-war recovery.
Challenges and Uncertainties
The exact value and volume of Ukraine’s mineral wealth remain unclear, with extraction requiring significant capital investment, as noted by industry experts in NBC News (What to Know About Ukraine’s Mineral Wealth). Classified data for some minerals, ongoing conflict, and corruption challenges further complicate development. The controversy over resource control, with estimates varying (e.g., SecDev’s $12.4 trillion vs. 40% metal resources), highlights the need for diplomatic and economic strategies to resolve access issues.
Conclusion
Ukraine’s REE resources are a critical asset, distributed across regions like Donetsk, Luhansk, and Poltava, with control split between Ukraine (approximately 60%) and Russia (approximately 40%). This division reflects broader geopolitical tensions, with significant implications for global supply chains and Ukraine’s economic future. As of April 28, 2025, ongoing efforts to develop Ukrainian-controlled deposits and international partnerships offer hope, but the conflict continues to shape resource access and control.
The U.S. government maintains a Critical Minerals List, which identifies minerals and materials deemed essential to economic and national security, with supply chains vulnerable to disruption. As of the latest updates from the U.S. Geological Survey (USGS) and the Department of Energy (DOE), the 2022 Critical Minerals List includes 50 minerals considered critical. These minerals are vital for industries such as technology, defense, energy, and manufacturing, and their supply is at risk due to geopolitical, economic, or environmental factors. Ukraine, as noted in the prior response, possesses 23 of these critical minerals, making it a significant player in global supply chains.
Below is a comprehensive expansion of the 50 critical minerals as defined by the U.S. government, their uses, global supply dynamics, and Ukraine’s role in their production, with a focus on Rare Earth Elements (REE) as requested. The analysis includes detailed tables, bullet points, and Ukraine-specific data on resource distribution, control, and geopolitical implications.
Overview of the U.S. Critical Minerals List
The 2022 USGS Critical Minerals List, established under the Energy Act of 2020, identifies 50 minerals based on three criteria:
Essentiality: The mineral is critical for economic or national security functions.
Supply Risk: The mineral’s supply chain is vulnerable to disruption (e.g., reliance on foreign sources).
No Substitutes: The mineral lacks viable substitutes for its key applications.
These minerals are used in technologies like semiconductors, batteries, renewable energy systems, aerospace, and defense systems. The list is reviewed every three years, with the next update expected in 2025. The 50 minerals include individual elements, groups like REE, and Platinum Group Metals (PGMs).

As of April 28, 2025, leveraging these resources requires resolving conflict-related disruptions and securing international investment.
Extracting Rare Earth Elements (REEs) is a complex and resource-intensive process due to their low concentrations in ores, chemical similarities, and association with other minerals. Ukraine’s REE deposits, such as the Novopoltavske deposit in Poltava (Ukraine-controlled) and the Shevchenko Field in Donetsk (partly Russia-controlled), are primarily found in phosphate ores, lithium ores, and titanium-bearing minerals. Below is a comprehensive explanation of specific REE extraction methods, tailored to the context of Ukraine’s deposits where applicable, with detailed descriptions, bullet points, and tables to outline processes, challenges, and considerations.
Overview of REE Extraction
REE extraction involves three main stages:
Mining: Extracting ore from the ground.
Beneficiation: Concentrating REE-bearing minerals from the ore.
Hydrometallurgical or Pyrometallurgical Processing: Separating and purifying individual REEs.
The choice of method depends on the ore type (e.g., phosphate, monazite, bastnäsite, xenotime), deposit geology, and economic factors. Ukraine’s REEs are often coproducts of phosphate or lithium ores, requiring tailored approaches.
Specific REE Extraction Methods
1. Mining
Mining is the first step, accessing REE-bearing ores. Ukraine’s deposits vary by region, influencing the mining method.
Open-Pit Mining:
Used for: Shallow deposits, like Novopoltavske (Poltava), where phosphate ores with REE coproducts are near the surface.
Process:
Remove overburden (soil/rock) using heavy machinery.
Extract ore via drilling, blasting, and excavation.
Transport ore to processing facilities.
Advantages:
Cost-effective for large, near-surface deposits.
High production rates.
Challenges:
Environmental impact (land disturbance, dust, water use).
Ukraine’s conflict zones (e.g., Donetsk) may limit access to equipment and infrastructure.
Ukraine Relevance: Likely used for Novopoltavske due to its phosphate ore characteristics.
Underground Mining:
Used for: Deeper deposits, potentially in Donetsk (Shevchenko Field) for lithium-REE ores.
Process:
Create tunnels/shafts to access ore.
Use selective mining to extract REE-rich veins.
Transport ore to surface for processing.
Advantages:
Less surface disruption than open-pit.
Suitable for high-value, concentrated deposits.
Challenges:

2. Beneficiation
Beneficiation concentrates REE-bearing minerals (e.g., monazite, bastnäsite, xenotime) from raw ore, reducing waste before chemical processing. Ukraine’s phosphate and lithium ores require specific techniques.
Physical Separation:
Techniques:
Gravity Separation: Uses density differences to separate heavy REE minerals (e.g., monazite, density ~5 g/cm³) from lighter gangue (e.g., quartz, ~2.6 g/cm³). Common for phosphate ores in Poltava.
Magnetic Separation: Exploits magnetic properties of REE minerals (e.g., monazite is weakly magnetic) to separate from non-magnetic materials.
Flotation: Uses chemical reagents to make REE minerals hydrophobic, allowing them to float and be skimmed off. Effective for fine-grained ores.
Process:
Crush and grind ore to liberate REE minerals (typically <100 microns).
Apply separation techniques in sequence (e.g., gravity followed by flotation).
Produce a concentrate (~30-60% REE oxides).
Ukraine Relevance:
Novopoltavske’s phosphate ores likely contain monazite, suitable for flotation and gravity separation.
Shevchenko Field’s lithium-REE ores may require magnetic separation for associated REE minerals.
Challenges:
Low REE concentrations (often <1% in ore) require large ore volumes.
Energy-intensive crushing and grinding.
Radioactive byproducts (e.g., thorium, uranium in monazite) need safe handling, a concern for Ukraine’s deposits.

3. Hydrometallurgical Processing
Hydrometallurgy is the primary method for extracting and separating individual REEs from concentrates, using chemical leaching and solvent extraction. It is widely used globally and applicable to Ukraine’s deposits.
Acid Leaching:
Used for: Monazite, bastnäsite, and phosphate ores (e.g., Novopoltavske).
Process:
Treat concentrate with sulfuric acid (H₂SO₄) or hydrochloric acid (HCl) at high temperatures (100-200°C) to dissolve REEs into a solution.
Ore Type: Lithium ores with REE coproducts, likely requiring underground mining and magnetic separation.
Control: Eastern parts under Russia, complicating extraction (Al Jazeera).
Challenges: Conflict disrupts operations; limited data on REE grades.
Other Regions (Dnipropetrovsk, Kirovohrad):
Ore Type: Titanium and nickel-cobalt ores with REE coproducts.
Control: Ukraine-controlled, less developed.
Methods: Likely flotation and acid leaching, but smaller scale.
Challenges in REE Extraction
Low Concentrations: REEs are often <1% of ore, requiring large-scale processing (e.g., 1000 tons of ore for 1 ton of REE oxides).
Environmental Impact: Acid leaching and radioactive waste (thorium, uranium) pose risks, critical for Ukraine’s post-conflict recovery.
Geopolitical Barriers: Russia’s control of ~40% of Ukraine’s REE deposits (e.g., Donetsk) limits access, as noted by BBC (What Minerals Does Ukraine Have?).
Cost: Extraction costs $10-50/kg for REE oxides, with high capital investment needed.
Conclusion
REE extraction methods include mining (open-pit or underground), beneficiation (gravity, magnetic, flotation), and hydrometallurgical processing (acid/alkaline leaching, solvent extraction), with pyrometallurgy and emerging techniques like bioleaching as alternatives. Ukraine’s Novopoltavske deposit is suited for open-pit mining and acid leaching, while Shevchenko Field may require underground mining and magnetic separation, though Russian control complicates access. As of April 28, 2025, developing Ukraine’s REEs requires investment in infrastructure, environmental management, and resolution of geopolitical conflicts to leverage its ~60% controlled deposits for global supply chains.
China’s dominance in critical minerals, particularly Rare Earth Elements (REEs) and other strategic metals, is a result of decades of deliberate industrial policies, lax environmental regulations, and strategic investments. This dominance grants China significant control over global supply chains for technologies critical to electronics, renewable energy, defense, and manufacturing. Below is a comprehensive expansion on China’s mineral dominance, focusing on REEs as requested, while also covering other critical minerals, their applications, global supply dynamics, and implications for regions like Ukraine. The analysis includes detailed bullet points, tables, and insights into geopolitical and economic ramifications, drawing on the provided web and X post references where relevant.
Overview of China’s Mineral Dominance
China accounts for approximately 60-70% of global REE production and 85-90% of REE refining, alongside significant shares in other critical minerals like lithium, cobalt, nickel, graphite, and antimony. This dominance stems from:
Geological Resources: China holds ~36.7% of global REE reserves, alongside substantial deposits of other minerals (CSIS China Power).
Industrial Policies: Since the 1980s, China has used subsidies, export restrictions, and tax rebates to build its mineral industry (Visual Capitalist).
Cost Advantages: Low labor costs and lax environmental standards allowed China to outcompete Western producers, who faced stricter regulations (Reuters).
Technological Expertise: China has filed over 25,000 REE patents (1950-2018), surpassing the U.S.’s 10,000, and perfected processes like solvent extraction (New Security Beat).
China’s control extends beyond mining to refining, processing, and downstream manufacturing (e.g., magnets, batteries), making it the linchpin of global supply chains. This has raised concerns in the West, particularly the U.S. and EU, about supply chain vulnerabilities, especially given China’s willingness to use export bans as geopolitical leverage (BBC).

Notes:
REEs: China’s monopoly is strongest in heavy REEs (e.g., dysprosium, terbium), controlling ~100% of global processing (Politico).
Battery Minerals: China’s refining dominance in lithium, cobalt, and nickel gives it control over ~70% of global EV battery production (ABC News).
Semiconductor Minerals: Gallium and germanium are critical for chips, and China’s export restrictions (2023-2024) have disrupted U.S. and EU supplies (CSIS).
China’s REE Dominance
REEs are a group of 17 elements critical for high-tech applications (see previous response for detailed applications). China’s dominance in REEs is particularly pronounced due to:
Mining: ~70% of global REE ore extraction, down from 97.7% in 2010 due to increased non-China production (CSIS China Power).
Refining: ~90% of global REE processing, including 100% of heavy REEs like dysprosium and terbium (New Security Beat).
Magnets: ~90% of permanent magnets (e.g., neodymium-iron-boron, samarium-cobalt) used in EVs, wind turbines, and defense systems (The Graduate Press).
Recent Discoveries: A 2025 discovery in Yunnan province could yield 470,000 tonnes of middle and heavy REEs (praseodymium, neodymium, dysprosium, terbium), reinforcing China’s position (Mining.com).
How China Achieved REE Dominance
1980s-1990s Policies: Deng Xiaoping’s 1980s declaration, “The Middle East has oil; China has rare earths,” spurred heavy subsidies and export tax rebates, enabling China to capture market share (Zimtu Capital).
Environmental Leniency: Lax regulations allowed cost-competitive mining and processing, driving out Western competitors like the U.S.’s Mountain Pass mine by the 1990s (Forbes).
Market Flooding: China flooded global markets with low-priced REEs in the 1980s, undermining competitors (Politico).
Consolidation: The 2021 creation of China Rare Earth Group, merging three state-owned enterprises, gave China control over ~25% of global REE resources (Baker Institute).
Technological Advancements: Over 30 years of R&D, including 25,000+ patents, perfected solvent extraction, a key refining process (X Post @tphuang).
REE Applications and Strategic Importance
Electronics: Neodymium, praseodymium, and dysprosium in magnets for smartphones, hard drives, and speakers.
Renewable Energy: Neodymium and dysprosium in EV motors and wind turbine magnets (e.g., 600kg REEs per 3MW turbine).
Defense: Heavy REEs (dysprosium, terbium) in F-35 jets (~420kg per jet), missile guidance, and radar systems (BBC).
Medical: Gadolinium in MRI contrast agents, lutetium in PET scans.
Geopolitical Leverage: China’s export bans (e.g., 2010 to Japan, 2023-2025 to U.S.) demonstrate its ability to disrupt global supply chains (CSIS).
Other Critical Minerals
China’s dominance extends to minerals critical for batteries, semiconductors, and industrial applications:
Lithium: China refines 59% of global lithium, controlling EV battery production despite mining only 13% (ABC News).
Cobalt: Refines 73% of global cobalt, sourced largely from the DRC, used in EV batteries and superalloys.
Nickel: Processes 68% of global nickel, critical for stainless steel and batteries.
Graphite: Controls 90% of global processing, essential for EV battery anodes (X Post @RothLindberg).
Gallium and Germanium: ~95% and ~70% of global production, respectively, used in semiconductors and fiber optics. Export restrictions since 2023 have impacted U.S. chip production (Wired).
Antimony: ~70% of refining, used in flame retardants and batteries, with export bans escalating trade tensions (Wired).
Implications for Ukraine
Ukraine’s critical mineral resources, including REEs, are significant in the context of China’s dominance, as they offer a potential alternative supply source. Key points:
REE Deposits:
Novopoltavske (Poltava): Phosphate ores with monazite/xenotime, fully Ukraine-controlled, suitable for sulfuric acid leaching (Ukrainian Geologic Survey).
Shevchenko Field (Donetsk): Lithium-REE ores, under Russian control in eastern Donetsk, limiting Ukraine’s access (Al Jazeera).
Other regions (Dnipropetrovsk, Kirovohrad) hold REEs as coproducts in titanium and nickel-cobalt ores, all Ukraine-controlled.
Control Split: Ukraine controls ~60% of its REEs, while Russia occupies ~40% (e.g., eastern Donetsk, Luhansk) (BBC).
Geopolitical Role: Ukraine’s REEs could reduce Western reliance on China, with the U.S. pursuing a minerals deal to develop Ukrainian deposits (BBC). This aligns with efforts to diversify supply chains (Reuters).
Challenges:
Ukraine lacks advanced refining infrastructure, relying on methods like acid leaching and flotation, which are less efficient than China’s solvent extraction (New Security Beat).
Conflict disrupts mining in Donetsk and Luhansk, and radioactive waste from monazite ores requires careful management.
Investment needs are high, with extraction costs of $10-50/kg for REE oxides (NBC News).
Global Responses to China’s Dominance
China’s control has prompted Western efforts to diversify supply chains, with mixed success:
United States:
Revived Mountain Pass mine (15% of global REE production) but sends ore to China for processing (Politico).
Biden’s Defense Production Act funds REE projects, and Trump’s 2025 tariff probes aim to boost domestic production (Wired).
DARPA’s EMBER program explores bioleaching for sustainable REE processing, though scalability is 4-5 years away (New Security Beat).
Europe:
Norway’s Fen Carbonatite Complex (8.8 megatons of REE oxides) could supply 10% of EU magnet-related REEs by 2030 (Newsweek).
EU’s Critical Raw Materials Act (2024) mandates 10% domestic sourcing and limits reliance on any single country to 65% (Newsweek).
Australia and Canada:
Australia funds REE processing (e.g., Iluka Resources) and partners with the U.S. (War on the Rocks).
Canada supports mining but lacks refining capacity (Reuters).
Japan:
Aims to reduce China’s REE import share to <50% by 2025 through recycling and partnerships with Vietnam (Visual Capitalist).
Ukraine:
U.S.-Ukraine mineral agreement (2024) targets REE and lithium development to counter China’s dominance (Reuters).
Poltava’s Novopoltavske deposit is open for investment, but conflict and infrastructure gaps hinder progress (Ukrainian Geologic Survey).
Despite these efforts, China’s refining dominance (85% for REEs, 90% for graphite) is unlikely to diminish significantly before 2030 due to long lead times for new facilities (Oxford Institute for Energy Studies).
Geopolitical and Economic Implications
Supply Chain Vulnerabilities:
China’s export restrictions (e.g., 2010 to Japan, 2023-2025 to U.S.) cause price spikes and shortages, impacting U.S. defense (F-35 jets, missiles) and manufacturing (CSIS).
X posts highlight concerns: “China has >95% control over these minerals and their refinement” (@SpencerHakimian).
Trade Weaponization:
China’s 2025 ban on seven REEs (samarium, gadolinium, terbium, dysprosium, lutetium, scandium, yttrium) in response to U.S. tariffs disrupts defense and tech sectors (CSIS).
Past bans on gallium, germanium, and graphite (2023-2024) targeted U.S. semiconductor and EV industries (Wired).
Economic Leverage:
China’s control over ~70% of EV battery production and 90% of permanent magnets gives it pricing power, affecting global markets (ABC News).
Low REE prices (“earth prices”) benefit China’s domestic industries but deter Western investment (Foreign Policy Research Institute).
Ukraine’s Role:
Ukraine’s REEs (~60% controlled) could diversify supply, but Russian occupation of ~40% (e.g., Shevchenko Field) and lack of refining capacity limit impact (Al Jazeera).
U.S. interest in Ukraine’s minerals aims to counter China, but conflict and environmental challenges (e.g., radioactive waste) pose risks (NBC News).
Challenges to China’s Dominance
Environmental Costs: REE mining and processing generate radioactive waste (thorium, uranium), drawing criticism and pushing China to tighten regulations (Reuters).
Western Diversification: Norway, Australia, and Ukraine’s deposits, alongside U.S. R&D (e.g., DARPA’s EMBER bioleaching), aim to erode China’s monopoly (Newsweek).
Market Dynamics: China’s export bans may backfire by spurring non-China production, as seen after 2010 when global mining share dropped from 97.7% to 62.9% (CSIS China Power).
Economic Risks: China’s slowing economy and declining exports could limit its ability to sustain bans, as noted by Forbes (Forbes).
Conclusion
China’s dominance in critical minerals, particularly REEs (60-70% production, ~90% refining), stems from strategic policies, cost advantages, and technological prowess, granting it control over global tech, energy, and defense supply chains. Its influence extends to lithium, cobalt, nickel, graphite, and semiconductor minerals, with export bans used as geopolitical tools. Ukraine’s REEs (60% Ukraine-controlled, ~40% Russia-controlled) offer a potential counterweight, but conflict, infrastructure gaps, and environmental challenges limit its role. Western efforts to diversify (e.g., U.S., EU, Australia) face long lead times, ensuring China’s dominance persists through 2030. As of April 28, 2025, China’s mineral control remains a critical issue, with Ukraine’s resources part of a broader strategy to reduce reliance on Beijing.
Thorium, a naturally occurring radioactive element, is a critical mineral with significant potential as a future nuclear fuel source, particularly for thorium-based reactors, which are considered safer and more efficient than uranium-based reactors, producing less nuclear waste. Thorium is three to four times more abundant than uranium in the Earth’s crust, with global resources estimated at over 6.3 million tonnes, distributed across countries like India, Brazil, Australia, the United States, and China. In Ukraine, thorium is primarily associated with Rare Earth Element (REE) deposits, such as monazite in phosphate ores, but recent data on thorium-specific discoveries or commercial viability is limited due to outdated geological surveys and the ongoing conflict. This response expands on thorium deposits globally and in Ukraine, focusing on their geological context, extraction methods, association with REEs, control status in Ukraine, and geopolitical implications, with detailed bullet points and tables.
Global Thorium Deposits
Geological Context
Thorium is a lithophilic element, meaning it has a strong affinity for oxygen and integrates into silicate melts, concentrating in the lithosphere. It is found in various geological environments:
Primary Deposits:
Carbonatites: Igneous rocks rich in carbonates, often containing thorium in monazite or bastnäsite (e.g., Bayan Obo, China).
Alkaline Rocks and Pegmatites: Thorium concentrates in late-stage magmatic melts, forming minerals like thorite or monazite (e.g., Lemhi Pass, USA).
Vein Deposits: Thorium occurs in hydrothermal veins with REEs and uranium (e.g., Nolans Bore, Australia).
Secondary Deposits:
Placer Deposits: Weathering of primary rocks deposits thorium-rich monazite in coastal or alluvial sands (e.g., India’s eastern coast, Brazil).
Key Minerals:
Monazite: A phosphate mineral containing 2.5–10% thorium oxide (ThO₂), the primary thorium source globally, often co-occurring with REEs.
Thorite (ThSiO₄): Contains up to 12% ThO₂, found in igneous rocks.
Thorianite (ThO₂): Rare, high-thorium mineral, often mixed with uranium oxides.
Abundance: Thorium concentrations in the Earth’s crust average 8–12 ppm, compared to uranium’s 2–4 ppm, with higher concentrations in granites (13–56 ppm) and carbonatites (up to 20%).
Global Reserves
The International Atomic Energy Agency (IAEA) and Nuclear Energy Agency (NEA) estimate global thorium resources at over 6.3 million tonnes, with reserves (commercially viable deposits) concentrated in a few countries. The table below summarizes key thorium reserves by country, based on IAEA data and recent reports.

Notes:
India: Holds the largest reserves, with 72% in eastern coastal states, driven by monazite placer deposits. India’s thorium reactor program aims to leverage these for energy security.
China: A 2025 discovery at Bayan Obo could yield 1 million tonnes, potentially meeting China’s energy needs for 60,000 years via thorium molten salt reactors.
Ukraine: Thorium data is sparse, primarily a byproduct of REE deposits like Novopoltavske (Poltava) and Shevchenko Field (Donetsk), with no recent discoveries reported.
Extraction Methods
Thorium is typically extracted as a byproduct of REE or uranium mining, using methods similar to those for REEs (see previous response for REE extraction details). Specific methods for thorium include:
Mining:
Open-Pit: For placer deposits (e.g., India’s coastal sands) or shallow carbonatites (e.g., Bayan Obo, China).
Underground: For vein or alkaline rock deposits (e.g., Lemhi Pass, USA).
Beneficiation:
Gravity Separation: Separates heavy monazite (density ~5 g/cm³) from lighter gangue in placer deposits.
Flotation: Concentrates monazite from phosphate or carbonatite ores using chemical reagents.
Magnetic Separation: Isolates monazite from other heavy minerals.
Hydrometallurgical Processing:
Sulfuric Acid Leaching: Dissolves monazite to extract thorium and REEs (e.g., Monazite + H₂SO₄ → Th sulfate + REE sulfates).
Alkaline Leaching: Uses sodium hydroxide to convert thorium phosphates to hydroxides, followed by acid leaching.
Solvent Extraction: Separates thorium from REEs and uranium using organic solvents like tributyl phosphate.
Challenges:
Radioactive waste (thorium, uranium) requires secure disposal, a concern for Ukraine’s monazite-rich ores.
High processing costs due to low thorium concentrations (2.5–10% in monazite).
Environmental regulations in Western countries increase costs, favoring China’s lax standards.
Thorium Deposits in Ukraine
Geological Context
In Ukraine, thorium is primarily a byproduct of REE deposits, particularly in monazite, which is associated with phosphate ores, lithium ores, and titanium-bearing minerals. Key regions include:
Poltava: Novopoltavske deposit, phosphate ores with monazite, fully Ukraine-controlled.
Donetsk: Shevchenko Field, lithium ores with REE-thorium coproducts, under Russian control in eastern parts.
Dnipropetrovsk, Kirovohrad, Zhytomyr: Titanium and nickel-cobalt ores with minor thorium, Ukraine-controlled.
Ukrainian Shield: South-central region hosts REE-thorium deposits of volcanic origin, often with uranium.
Thorium occurs in:
Monazite: Primary thorium mineral, found in phosphate ores (e.g., Novopoltavske) and heavy mineral sands.
Zircon and Allanite: Minor thorium content (0.1–0.4%) in titanium and REE deposits.
Uranium Deposits: Thorium is a coproduct in Na-metasomatite uranium deposits (e.g., Central Ukrainian Uranium Province).
Reserves and Recent Discoveries
Reserves: Ukraine’s thorium reserves are not quantified in modern assessments due to reliance on Soviet-era data (30–60 years old) and lack of recent exploration. Estimates suggest thorium is present in REE deposits, but commercial viability is unconfirmed.
Recent Discoveries: No specific thorium discoveries have been reported in Ukraine as of April 28, 2025. The search results mention global thorium finds (e.g., China’s Bayan Obo) but lack Ukraine-specific data. Soviet and Ukrainian geoscientists identified thorium in REE and uranium deposits, but these remain undeveloped due to outdated geologic data and war-related disruptions.
Data Gaps: The Ukrainian Geological Survey notes no modern thorium or REE reserve assessments, with S&P Global reporting no active thorium or lithium projects in Ukraine.
Control Status
Ukraine’s thorium, as a byproduct of REEs, follows the same control split as REE deposits:
Ukraine-Controlled (~60%):
Poltava (Novopoltavske): Fully Ukraine-controlled, phosphate ores with monazite-thorium, open for investment.
Dnipropetrovsk, Kirovohrad, Zhytomyr: Titanium and nickel-cobalt deposits with minor thorium, fully Ukraine-controlled.
Western Donetsk, Kharkiv: Smaller thorium-bearing REE deposits, Ukraine-controlled.
Luhansk: Most REE-thorium deposits occupied by Russia.
Parts of Zaporizhzhia: Minor thorium in REE deposits, Russian-controlled.

Extraction in Ukraine
Thorium extraction in Ukraine would mirror REE methods, as it is a byproduct of monazite processing:
Mining: Open-pit for Novopoltavske’s phosphate ores; underground for Shevchenko Field’s lithium-REE ores (if accessible).
Beneficiation:
Flotation and gravity separation to concentrate monazite from phosphate or heavy mineral sands.
Magnetic separation for titanium-REE ores in Dnipropetrovsk and Zhytomyr.
Hydrometallurgical Processing:
Sulfuric acid leaching to extract thorium and REEs from monazite (e.g., Novopoltavske).
Solvent extraction to separate thorium from REEs and uranium, requiring advanced facilities not currently available in Ukraine.
Challenges:
Radioactive waste management (thorium, uranium) is critical, especially for monazite-rich ores.
Conflict disrupts infrastructure, particularly in Russian-controlled Donetsk and Luhansk.
Lack of modern geological data hinders commercial viability assessments.
Geopolitical and Economic Implications
Global Context
Energy Potential: Thorium’s role in molten salt reactors could revolutionize nuclear energy, with China leading development (e.g., Bayan Obo’s 1M-tonne discovery). India’s thorium program also leverages its vast reserves.
China’s Dominance: China’s control of ~90% of REE refining and significant thorium reserves (potentially 1M tonnes) gives it strategic leverage, especially with export bans on REEs and related minerals. Ukraine’s thorium could diversify supply, reducing reliance on China.
Western Interest: The U.S. and EU see Ukraine’s REE-thorium deposits as a counter to China’s monopoly, with a 2024 U.S.-Ukraine minerals deal targeting joint development. However, outdated data and war-related risks deter investment.
Ukraine-Specific Implications
Economic Potential: Thorium, as a byproduct of REE mining, could enhance Ukraine’s mineral revenue, estimated at $15 trillion for all critical minerals. However, no active thorium projects exist, and commercial extraction is likely 15–20 years away.
Geopolitical Barriers: Russia’s control of ~40% of Ukraine’s metal resources, including thorium-bearing REE deposits in Donetsk and Luhansk, limits access and revenue. This strengthens Russia’s position in global mineral markets.
Environmental Concerns: Thorium extraction from monazite produces radioactive waste, requiring stringent regulations and infrastructure Ukraine currently lacks, especially in conflict zones.
Investment Needs: Developing thorium and REE deposits requires $500M–$1B per mine, plus modern geological surveys, which Ukraine cannot fund without foreign partners. The U.S. deal aims to address this, but success hinges on peace and infrastructure restoration.
Thorium vs. Uranium in Ukraine
Uranium: Ukraine has significant uranium deposits (e.g., Central Ukrainian Uranium Province, ~300,000 tonnes), but only 2% of global economically recoverable resources, less strategic than Australia or Kazakhstan. Uranium is actively mined in Kirovohrad and Dnipropetrovsk.
Thorium: Less explored, with no quantified reserves, but potentially abundant as a monazite byproduct. Thorium’s future energy potential is high, but lack of commercial reactors limits current demand.
Challenges and Future Prospects
Data Limitations: Ukraine’s thorium data relies on Soviet-era surveys, with no modern assessments to confirm commercial viability. Recent global discoveries (e.g., China’s Bayan Obo) highlight the need for updated exploration.
Conflict: Russia’s occupation of Donetsk and Luhansk disrupts access to thorium-bearing REE deposits, and war damages infrastructure critical for mining.
Environmental Risks: Thorium extraction generates radioactive waste, requiring advanced disposal systems Ukraine lacks, especially in conflict zones.
Global Competition: China’s thorium and REE dominance, coupled with India’s reserves, overshadows Ukraine’s unquantified deposits. Western investment could shift this, but timelines are long.
Future Potential: If Ukraine conducts modern surveys and secures peace, thorium could enhance its role in global energy markets, particularly with U.S. and EU support for thorium reactor R&D.
Conclusion
Thorium deposits are globally abundant, with over 6.3 million tonnes in reserves, led by India, Brazil, Australia, the U.S., and China, which recently discovered a potential 1 million tonnes at Bayan Obo. In Ukraine, thorium is a byproduct of REE deposits (e.g., monazite in Novopoltavske, Shevchenko Field), with ~60% under Ukrainian control and ~40% in Russian-occupied regions like Donetsk and Luhansk. No recent thorium-specific discoveries are reported, and outdated Soviet-era data limits commercial prospects. Extraction methods mirror REE processes (open-pit mining, flotation, acid leaching), but conflict, infrastructure gaps, and radioactive waste challenges hinder development. Geopolitically, Ukraine’s thorium could counter China’s REE-thorium dominance, but significant investment and peace are prerequisites. As of April 28, 2025, thorium remains a long-term prospect for Ukraine, tied to its REE industry and global energy transitions.
