Method for extraction of beryllium from the minerals of genthelvite group when processing the raw Method for extraction of beryllium from minerals of bertrandite and phenakite groups when processing the raw minerals (ores, concentrates)

摘要

The invention relates to the non-ferrous metallurgy industry and can be used for extracting beryllium from bertrandite and phenakite groups under conditions of processing of mineral raw materials (ore, concentrate) by heap, vat leaching.

主权项

1. A method for leaching beryllium (bertrandite and phenakite groups) from a beryllium-containing concentrate or an ore, comprising:
contacting the concentrate or the ore with a leaching solution, containing technical hydrochloric acid and extracting beryllium via heating for 8 hours at 80° C., wherein the technical hydrochloric acid is used in amounts from 0.2-12% (by volume) per liter of leaching solution.
