METHOD OF PROCESSING OF THICKENING SULFUR-SULFIDE GOLD-CONTAINING CONCENTRATES Russian patent published in 2017 - IPC C22B11/08 C22B3/18 B03D1/00

Abstract RU 2621196 C2

FIELD: metallurgy.

SUBSTANCE: method includes preliminary opening of sulfides. After opening, flotation enrichment is carried out on organic carbon, sulfide and elemental sulfur and gold with the direction of the flotation concentrate for pyrometallurgical or pyrodiammetallurgical processing, and the chamber product of flotation for cyanidation. Opening of sulphides in an aqueous medium is carried out by bacterial, or autoclave, or acid-oxygen opening.

EFFECT: increasing the through-extraction of gold from concentrates by reducing the persistence of the product entering the cyanide.
