Rejection of Arsenopyrite in a High As-Containing Pyrite Concentrate by Inorganic Depressants

Abstract:

In order to utilize the high As-containing pyrite concentrate in Datun concentrator, SW China, flotation tests has been conducted by applying the inorganic depressants to produce a marketable product. By means of orthogonal experimental design, the optimized levels and main factors have been found for the roughing stage in flotation. Through selection of the effective inorganic depressants for arsenopyrites in flotation system, the main As-containing mineral (arsenopyrite) can be effectively depressed and separated from the said pyrite concentrate, containing 33.1% S, and only 0.48 % As by one-stage roughing and two-stage cleaning flotation operations
