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

Abstract

The invention relates to non-ferrous metallurgy and is used for extracting beryllium from genthelvites when processing the raw minerals (ores, concentrates) by heap and vat leaching. The objective of the invention is to disclose a method of leaching beryllium from danalite (Fe8(BeSiO4)6S2), genthelvite (Zn8(BeSiO4)6S2), and helvite (Mg8(BeSiO4)6S2), thus expanding the range of raw minerals used for processing and providing more economical production and improved environmental impact via use of an effective reagent at low temperatures by hydrochemical method. The offered method is beneficial both economically and ecologically, as the alternate modern pyrometallurgical method of beryllium extraction has the following drawbacks: emission of toxic gases, high energy requirements, and use of the fireproof materials. The newly developed method is recommended as a basis for the innovative technology of beryllium extraction from genthelvite concentrates and ores.
