Abstract: The present invention discloses methods for leaching beryllium from a beryllium-containing concentrate or a beryllium-containing ore, comprising contacting the concentrate or the ore with a leaching solution, wherein the leaching solution contains a technical grade hydrochloric acid, wherein the solution contains no sulfuric acid, no nitric acid, and no potassium chlorate, extracting beryllium via a gradual heating process, wherein the technical grade hydrochloric acid is used in varying amounts by volume per liter of leaching solution, and adding ammonium fluoride to the leaching solution in contact with the concentrate or ore, wherein the ammonium fluoride is added in a fractional manner.

Abstract: 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.

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.
