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.
