Which Country Has the Most Uranium? Kazakhstan Dominates Global Supply

For investors tracking the nuclear energy sector, understanding global uranium production patterns is essential. The answer to “which country has the most uranium production” is clear and decisive: Kazakhstan has held the position of world’s leading uranium producer since 2009, and this dominance shows no signs of weakening. In 2022, the most recent year with complete production data, Kazakhstan extracted 21,227 metric tons of uranium—accounting for an astounding 43 percent of the world’s total uranium supply. This commanding lead reflects both the nation’s abundant reserves and its strategic importance in the global nuclear fuel supply chain.

The global uranium market has undergone a dramatic transformation over the past 15 years. World production peaked at 63,207 metric tons in 2016, then contracted significantly to just 49,355 metric tons by 2022 as low spot prices rendered many mines uneconomical. The 2011 Fukushima disaster and chronic oversupply depressed demand for years. However, the tide turned sharply in 2021. Uranium prices surged to a 17-year high of $106 per pound in early 2024, driven by renewed interest in nuclear energy as a carbon-free power solution and mounting supply concerns from major producing nations. Prices have since stabilized around $70 per pound as of mid-2025, yet the market remains bullish due to persistent supply-demand imbalances.

Kazakhstan Leads by a Landslide

Kazakhstan’s uranium production dominance rests on geological advantage and operational expertise. The country possesses 815,200 metric tons of known recoverable uranium reserves—the second-largest deposit globally, trailing only Australia. Most extraction occurs through in-situ leaching, a cost-effective technique that minimizes environmental disruption. Kazatomprom, the state-owned national uranium miner, operates as the world’s largest uranium producer, managing projects and partnerships across multiple jurisdictions.

Kazatomprom’s most significant operation is the Inkai in-situ recovery mine, where the company holds a 60 percent stake alongside Canadian partner Cameco holding 40 percent. Inkai produced 8.3 million pounds of uranium oxide concentrate in 2023. Operations faced a temporary suspension in early 2025 due to regulatory delays, though this has since been resolved. Beyond existing mines, Kazatomprom is expanding capacity through major infrastructure investments. In May 2025, the company announced that its subsidiary’s 40 percent stake in Taiqonyr Qyshqyl Zauyty secured $189 million in financing from Kazakhstan’s Development Bank to construct an 800,000 metric-ton-per-year sulfuric acid production facility in the Turkestan region. This plant is scheduled for operation by Q1 2027, signaling management’s confidence in sustained uranium demand.

Canada Bouncing Back from Production Decline

Canada represents the second-largest uranium-producing country, with 2022 output of 7,351 metric tons. However, this figure masks a dramatic recovery story. Canadian uranium production collapsed from a 2016 peak of 14,039 metric tons as depressed prices forced mine closures throughout the late 2010s. Production began rebounding in 2022, signaling renewed market confidence. Saskatchewan hosts the world’s two richest uranium deposits: Cigar Lake and McArthur River, both operated by Cameco. Remarkably, these mines produce uranium grades averaging 100 times the global average, a geologic advantage that supports future profitability even at lower prices.

Cameco shuttered McArthur River operations in 2018 but restarted full production in November 2022 as market conditions improved. The company produced 17.6 million pounds of uranium in 2023—equivalent to 7,983 metric tons—which still fell short of its original 20.3 million pound guidance. However, 2024 showed improved execution, with Cameco extracting 23.1 million pounds, exceeding annual guidance. For 2025, the company plans to produce 18 million pounds at both the McArthur River/Key Lake complex and at Cigar Lake separately.

Beyond mining, Canada has become a center for uranium exploration, with most activity concentrated in Saskatchewan’s Athabasca Basin. This region enjoys international recognition for its high-grade deposits and mining-friendly regulatory environment, positioning Canada as a strategic uranium supplier as global nuclear capacity expands.

Namibia’s Growing Challenge

Namibia produced 5,613 metric tons of uranium in 2022, securing third place among producing countries. The African nation’s output has trended upward since bottoming at 2,993 metric tons in 2015. Namibia briefly overtook Canada to become the world’s third-largest producer in 2020, then captured the number-two position in 2021. Though it slipped back below Canada in 2022, the year-over-year decline was minimal—only 140 metric tons—indicating structural production strength.

Three major mines support Namibian output: Langer Heinrich, Rössing, and Husab. Paladin Energy owns the Langer Heinrich operation, which was taken offline in 2017 due to weak uranium prices. Improving market conditions inspired Paladin to restart the mine, achieving commercial production status again in Q1 2024. However, operational challenges have emerged. Paladin initially forecast 4 to 4.5 million pounds of uranium oxide for fiscal 2025 but revised guidance downward to 3 to 3.6 million pounds in November 2024 due to inconsistent ore stockpiles and water supply constraints. Then, after heavy rains disrupted operations in March 2025, Paladin withdrew guidance entirely, now facing two class action lawsuits related to the guidance revisions.

Rio Tinto divested its controlling stake in the Rössing mine to China National Uranium in 2019, but the operation continues as the world’s longest-running open-pit uranium mine. Recent expansion work has extended mine life through 2036. The Husab mine, majority-owned by China General Nuclear, ranks among the world’s largest by output. The operator is piloting a heap leach project to evaluate the economic feasibility of processing lower-grade ore, with results expected in 2025.

Australia’s Vast Resources, Limited Use

Australia extracted 4,087 metric tons of uranium in 2022, down from 6,203 metric tons in 2020. This decline reflects policy constraints rather than resource scarcity: Australia holds 28 percent of the world’s known recoverable uranium reserves, yet opposes nuclear power for domestic energy generation—at least officially. The World Nuclear Association notes that “Australia uses no nuclear power, but with high reliance on coal, any likely carbon constraints on electricity generation will make it a strong possibility.”

Australia hosts three operating uranium mines, including the planet’s largest-known uranium deposit: BHP’s Olympic Dam. Although uranium is merely a by-product at Olympic Dam alongside copper production, the mine’s scale makes it the world’s fourth-largest uranium mine by output. BHP reported uranium oxide concentrate production of 3,603 metric tons during its 2024 fiscal year from Olympic Dam operations alone.

Rising Producers: Uzbekistan, Russia, and Others

Uzbekistan emerged as the fifth-largest uranium-producing country in 2022 with output of 3,300 metric tons. The nation entered the top five in 2020 and has maintained steady production growth since 2016, achieved through Japanese and Chinese joint ventures. Navoiyuran, spun out of the state-owned Navoi Mining & Metallurgy Combinat in 2022, manages all domestic uranium mining and processing.

Uzbekistan continues attracting international investment. In November 2023 and March 2024, strategic partnerships with French uranium producer Orano and state-run China Nuclear Uranium were announced, respectively. Notably, Orano already maintains a 51 percent stake in Nurlikum Mining, a 2019 joint venture developing the South Djengeldi uranium project in the Kyzylkum Desert. In early 2025, Japan’s ITOCHU acquired an undisclosed minority stake in the project. South Djengeldi is projected to produce up to 700 metric tons annually over a lifespan exceeding ten years, with exploration programs targeting mineral resource expansion.

Russia ranked sixth with uranium production of 2,508 metric tons in 2022. Output has remained relatively stable since 2011, typically ranging between 2,800 and 3,000 metric tons annually. Rosatom, a subsidiary of ARMZ Uranium Holding, operates Russia’s Priargunsky mine and develops the Vershinnoye deposit in Southern Siberia. Despite earlier expectations for production increases, output actually declined by 338 metric tons between 2021 and 2022. However, Russia surpassed its uranium production target in 2023, exceeding expectations by 90 metric tons. Rosatom is developing new capacity, including Mine No. 6, which is scheduled to commence production in 2028.

Niger produced 2,020 metric tons of uranium in 2022, accounting for roughly 5 percent of global supply. The African nation operates two major uranium properties: the producing SOMAIR mine and the past-producing COMINAK mine, both subsidiaries of French producer Orano. Global Atomic is developing the Dasa project and expects to commission its processing plant by early 2026. However, Niger’s uranium sector faces significant headwinds. A military coup in 2023 has reshaped policy. In January 2024, the military junta government announced intentions to overhaul the mining industry, halting new mining license issuances and revising existing arrangements to boost state revenue. By mid-2024, Niger revoked GoviEx Uranium’s Madaouela mining license and Orano’s operating permit for the Imouraren project. Subsequently, Niger granted a small-scale mining permit for the Moradi uranium project to state-owned COMIREX, approved February 22, 2025, which strengthens national control over uranium resources.

China and India Race for Energy Independence

China produced 1,700 metric tons of uranium in 2022, up 100 metric tons from 2021. Output climbed steadily during the 2010s from 885 metric tons in 2011 to 1,885 metric tons in 2018, then held relatively flat until declining to 1,600 metric tons in 2021. China General Nuclear Power, the country’s sole domestic uranium supplier, is expanding nuclear fuel supply agreements with Kazakhstan, Uzbekistan, and international uranium companies. China’s strategic goal envisions domestic producers supplying one-third of nuclear fuel cycle uranium, foreign equity mines and joint ventures providing another third, and open market purchases comprising the final third.

China is simultaneously a global nuclear energy leader: the Chinese mainland operates 56 nuclear reactors with 31 additional reactors under construction. In May 2025, Chinese scientists announced breakthrough results from a novel uranium extraction method employing seawater, utilizing hydrogel beads made with candle wax and uranium-binding compounds. Researchers aim to construct a demonstration plant by 2035, potentially unlocking vast uranium resources from ocean reserves to support China’s nuclear expansion.

India produced 600 metric tons of uranium in 2022, maintaining production levels from 2021. The country currently operates 25 nuclear reactors with eight additional units under construction. In 2025, India’s Minister for Power released a strategic roadmap to increase nuclear energy capacity to 100 gigawatts by 2047. The Indian government has committed to accelerated nuclear power growth as a cornerstone of its infrastructure development program.

South Africa’s Marginal but Growing Role

South Africa rounded out the top 10 uranium-producing countries with 200 metric tons extracted in 2022. South African output has steadily declined over the past decade from a 2014 peak of 573 metric tons. Nonetheless, improved performance relative to Ukraine—whose production was constrained by Russia’s invasion—elevated South Africa to tenth place. The country holds 5 percent of the world’s known uranium reserves, ranking sixth globally.

Recently, South African mining company Sibanye-Stillwater partnered with C5 Capital, a specialized investment firm focused on advanced nuclear energy, to explore and develop nuclear projects across South Africa and internationally. The collaboration seeks to identify, acquire, finance, develop and operate uranium projects and production facilities capable of supplying fuel for small modular reactors. Sibanye-Stillwater’s portfolio includes significant uranium resources within tailings at its Cooke and Beatrix gold mining operations, representing latent production capacity.

Why Understanding Uranium-Producing Countries Matters

The global uranium market is entering a new phase. After years of oversupply and depressed pricing, nuclear energy’s emergence as a critical climate solution is reshaping demand dynamics. Kazakhstan maintains its commanding lead as the world’s primary uranium supplier, but competitive positioning among other top-producing countries is shifting. For investors navigating the nuclear energy transition, tracking which countries produce the most uranium—and monitoring operational, geopolitical, and technological developments at major mines—remains essential to identifying opportunities and managing risks in this vital sector.
