METHOD OF EXTRACTION OF METALS FROM COPPER-SULFIDE AND / OR COPPER-IRON SULFUR ORES

摘要

The method of extracting metals from copper-sulphide and / or copper-iron-sulphide ores by leaching, by microbiological or chemical method for dissolving metals, in which, at the first leaching stage of the proposed process of transformation, the ore is converted into covellin, pyrite and related sulfides and recovered copper and other metals, noble metals, and rare earth elements contained in the reaction product. The international application was published along with an international search report.
