METHOD FOR ELECTROCHEMICAL HEAP LEACHING OF METALS Russian patent published in 1997 - IPC

Abstract RU 2087696 C1

FIELD: mining industry. SUBSTANCE: this relates to geotechnology and can be used in selective leaching and hydrometallurgical processing of gold-containing pyrite-polymetallic ores. According to method, created are antifiltration base, leaching pile. Electrodes are installed, alternate and direct current is supplied to electrodes, and material is treated by leaching solutions. In leaching gold-containing pyrite-polymetallic ores, initially leached out is copper. For this purpose, delivered are solutions of sulfuric acid. Then lead is leached out by treating with electric current, and after that gold is extracted by treating with direct electric current. EFFECT: high efficiency. 1 dwg
