Annotation:

The aim of the work is to develop an effective and environmentally sound method for extracting copper and removing arsenic from copper arsenic concentrates by chlorinating firing with sodium chloride. The influence of the main factors – temperature, roasting holding time and the ratio of the mass of the chlorinating reagent sodium chloride to the mass of the concentrate on the rate of the oxidizing-chlorinating roasting of concentrates has been studied. The concentrate firing process was carried out in two modes - with and without air supply. The study of the influence of a single factor from the above on the chlorination firing process was carried out with the consistency of others. Optimal process conditions have been determined to ensure a high yield of the target product.

Keywords: copper-arsenic sulfide concentrate, chlorination roasting, sodium chloride, copper concentrate production prospects.
