In 2015, China was an afterthought for beryllium production, producing less than 10% of what the U.S. produced — 20 tons compared to the U.S.' 275 tons. Source: Minerals Make Life. Flashforward to 2021, and in just seven years, U.S. production cratered, while China's more than tripled, closing the gap to within 100 tons.Web

The metal beryllium is mined by its extraction from the beryl ores. It does not occur free in nature. The mining of raw minerals such as bertrandite ore and beryl ore from the Earth's crust and volcanic rocks is required. Apart from beryl, beryllium is found in the mineral bertrandite, has become a major ore of the metal in the recent years.Web

Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore). Beryl ore is melted in industrial furnaces, solidified and crushed, then treated with sulfuric acid to produce a water-soluble sulfate. Bertrandite ore is crushed, made into slurry and treated with sulfuric acid to form a sulfate.Web
