Using a Modified Reagent in the Enrichment of Oxidized Copper Ores

Abstract

The problem of processing oxidized copper ores is acute in the copper industry of Kazakhstan. The solution to the problem of dressing oxidized ores is seen in changing the properties of oxidized minerals towards hydrophobization of the surface, which would increase the efficiency of the flotation method of dressing. Existing technologies for processing hard-to-enrich raw materials are energy-intensive, require a high consumption of reagents, or do not allow achieving high enrichment rates.This paper shows the results of studies aimed at solving the problem of increasing the efficiency of beneficiation of oxidized copper ores using a modified reagent for sulfidizing oxidized copper ores, which does not require forced heating of the pulp and the use of separate equipment. The results of the conducted flotation studies indicate the effectiveness of using the modified reagent in the beneficiation of oxidized copper ore of the Zhezkazgan deposit.
