Refined Selenium Reserves by Country
All nine reporters published a 2024 value — and none published one for 2025. The figures come from the USGS Mineral Commodity Summaries 2019-2026 and describe refined selenium reserves in metric tons. Reserves represent estimated quantities that can be economically extracted under applicable conditions, rather than the amount mined in a given year. For most countries, USGS estimates selenium reserves from the selenium content of identified copper reserves; China's figure represents reported selenium reserves. The table covers 9 countries, with listed reserves totalling 67,800 metric tons in the latest reported year, 2024. The listed total excludes 24,000 metric tons in 2024 reported under Other countries.
Russia (26,000 metric tons for 2024) leads Peru (16,000), with the pair holding about 61.9% of the listed total between them. The United States (10,000), Canada (6,500) and China (5,000) follow. Poland follows at 3,000, while India and Sweden each hold 500 and Finland 300. The top two countries hold about 61.9% of the listed 2024 reserves — nearly two-thirds in Russia and Peru. Every country's latest value is 2024: Russia 26,000, Peru 16,000, the United States 10,000, Canada 6,500, China 5,000, Poland 3,000, India and Sweden 500 each, Finland 300. The 2025 column is empty throughout — not zero anywhere, simply unpublished. Russia and Peru account for most of the movement: both were unchanged through 2022 before Russia rose to 26,000 and Peru moved to 19,000 in 2023, then fell to 16,000 in 2024. The remaining countries changed little by comparison, leaving the 2024 ranking broadly stable. Poland remained at 3,000 throughout its seven reported years. Figures come from the USGS Mineral Commodity Summaries 2019-2026. Units are metric tons of refined selenium, exactly as reported. No 2025 values were published, so the latest year shown is 2024 and shares are computed against the 2024 listed total. Empty means the source reported no value; 0 means the source reports zero. Reserves and production are different measures and should not be combined without equalizing units.

Methodology
Frequently Asked Questions
What are refined selenium reserves?
Refined selenium reserves are estimated quantities of refined selenium that can be economically extracted under applicable conditions, in metric tons. Production measures the amount mined in a year.
Which countries hold the most refined selenium reserves?
Russia (26,000 metric tons) and Peru (16,000) reported the largest 2024 values, followed by the United States (10,000).
Why is there no 2025 value?
USGS does not provide country-level selenium reserve values for 2025 in this series. The latest reported values are therefore from 2024; an empty cell means not reported, not zero.
What is the world total for refined selenium reserves?
USGS reports 92,000 metric tons for 2024, rounded in the source. Page shares use the listed-country total instead.
