ANALYZING THE PROCESSING METHODS OF OXIDIZED COPPER MINERALS BY MEANS OF SULPHITATION

Abstract

The analysis of sulphitation teachnologies of minerals has revealed that the existing methods of sulphitation of mineral surfaces do not provide the necessary efficiency as the formed sulphide membranes are easily decomposed during flotation. It is shown that the most efficient solution of the given problem is changing the mineralogical composition of the valuable components of the ore at its grinding by means of deep sulphitation of the oxidized mineral surfaces by using the SiS2, Na2S (Na2S-SiS2) sulphide systems.
