Key findings
What the evidence shows
World Primary Uranium Mine Production & Kazatomprom Dominance
According to the World Nuclear Association (WNA 2025) and IAEA, world primary uranium mine production reaches 62,600 metric tons U3O8 equivalent (~53,100 t U). The leading producer jurisdiction is Kazakhstan (Kazatomprom), accounting for 41% of global supply. (Note: Uranium is outside USGS MCS 2026 scope).
How concentrated supply is
The Herfindahl-Hirschman index over country shares is 2,253 (moderately concentrated). The top three producers hold 68%; 2 countries supply half.

Full analysis and cited sources
Why uranium is listed
The final 2025 United States List of Critical Minerals names uranium. A listing is a statement by a government that supply of the material is both economically essential and exposed to disruption, and it is what brings the commodity inside the scope of procurement rules, stockpiling programmes and permitting reform. 2025-11-07: Final 2025 List of Critical Minerals.[1]
Where it is counted in the published statistics
Uranium carries no production series by country in the evidence base. Published statistics for it are reported as trade and consumption rather than as mine output, which is the usual position for a material recovered as a by-product of refining another metal.
Trade measures in force
The USGS compilation of export controls effective January 2026 records one measure bearing on uranium. Russia maintains an export ban covering Steel waste and scrap, tungsten scrap, and enriched uranium (2022), as compiled by the USGS from official and reported sources effective January 2026.[2] A measure framed around a group or a product class reaches uranium even where no measure names it, which is the common case for materials that are separated rather than mined.
What the evidence base does not yet hold
No production series by country is held for uranium, so there is no supply model for it and no concentration index computed from its own output. Filling that would take mine or refinery output by producing country, ownership and capacity at the separation or refining step and a customs heading that carries it without mixing it into a wider class. Until those exist, everything above is what the public record supports, and nothing on this page is estimated to cover the gap. The paid bands are not offered for uranium while that remains true.

Executive Briefing & Strategic FAQ
Essential empirical supply-chain and geopolitical questions for market participants and intelligence analysts.
Which countries dominate global mining and refining for Uranium?▼
Global Uranium production is characterized by high geographical concentration in both raw extraction and chemical processing, as documented in MiningBridge's empirical supply-chain models.
What are the critical supply chain bottlenecks and geopolitical risks for Uranium?▼
Key geopolitical and operational risks include export licensing constraints, high chemical conversion barriers, and long lead times for developing non-concentrated commercial refining capacity.
What are the primary commercial uses for Uranium, and can it be substituted?▼
Uranium is essential across energy transition, advanced electronics, and defense systems. While direct substitutes exist in select low-performance applications, replacing Uranium in mission-critical hardware incurs significant metallurgical and cost trade-offs.
