Abstract

A process for extracting precious metals form ore that includes: collecting the ore, crushing the ore, enriching the ore using sulphuric acid at least in one washing cycle. Then precious metals are leached from the enriched ore by a non-aqueous solvent containing brome or bromide. The ore is than press filtered and direct electrical current is applied to the solvent bearing the precious metal, following which the metal is collected from the anode.
