US8945493B2 Method for extraction of beryllium from raw
The invention relates to non-ferrous metallurgy and can be used for extracting beryllium from genthelvite and bertrandite groups when processing the raw minerals (ores, concentrates) by heap and vat leaching. The objective of the invention is to disclose a method of teaching beryllium from danalite (Fe 8 (BeSiO 4 )6S 2 ), genthelvite (Zn 8 (BeSiO 4 )6S 2 ), helvite (Mg 8 (BeSiO 4 )6S 2

Beryllium Mining Processing Equipment Flow Chart
In addition to beryl, beryllium is found in the mineral bertrandite, which in recent years has become a major ore of this element. Bertrandite is found in certain volcanic rocks derived from granite. Bertrandite ore mined in Utah makes up nearly all of U.S. production, which is about 90% of the world supply.

Brush Wellman, Inc. bought the mineral rights to these dep osits and began mining in the 19 60's.5 Its plant in Delta, Utah, is the only commercial beryllium extraction and production plant operating in the Western world.6 The Delta plant uses both beryl and bertrandite ores as inputs for the production of beryllium hydroxide. While the bertrandite

Kazakhstan, and to China and Japan, for processing into beryllium metal and beryllium alloys. The annual mining and processing capacities are estimated to be 25,000 t/yr of bertrandite ore and 130 t/yr of beryllium hydroxide. Russia, in 2015, announced that it intended to produce beryllium metal on a commercial scale by 2020.

Beryllium Mining Mining Techniques and Processing
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. This bertrandite mineral is
