METHOD FOR PROCESSING OF OXIDATION PRODUCTS OF REFRACTORY SULPHIDE AURIFEROUS FLOTATION CONCENTRATES (VERSIONS) Russian patent published in 2017 - IPC C22B11/00 C22B3/04 C22B3/18

Abstract RU 2612860 C2

FIELD: metallurgy.

SUBSTANCE: group of inventions refers to non-ferrous metallurgy, in particular to the methods of processing oxidation products of refractory sulphide auriferous flotation concentrates. The method of processing oxidation products of refractory sulphide auriferous flotation concentrates includes dewatering of initial product taken as bio-pulp or autoclave pulp to give cake and centrate, and separate processing with the extraction of gold. Thus dehydration of bio-pulp or autoclave pulp is carried out by centrifugal separation to obtain cake and centrate. The resulting centrate is sent to further processing with the extraction of gold. The resulting cake is sent to further processing with the extraction of gold separated from the centrate.

EFFECT: invention provides an increase in gold extraction within the processing of bacterial or autoclave oxidation products of refractory sulphide auriferous flotation concentrates.
