METHOD FOR EXTRACTION OF GOLD FROM ORES Russian patent published in 1995 - IPC

Abstract RU 2040562 C1

FIELD: noble metal hydrometallurgy. SUBSTANCE: method involves grinding of ores; hydraulic classification and obtaining of silting fraction and sand; additional grinding of sands so that crystalline fraction is obtained; sorption cyaniding of silting and crystalline fraction so that tailings are obtained. Classification of silting fraction and and additional grinding of sands are followed by separating of sand fraction of +0.5 mm-size, which is further subject to passive cyanidation. Sorption cyanidation of silting and crystalline fractions is conducted on independent cycles. EFFECT: increased efficiency in extraction of gold. 2 cl, 1 tbl
