Experimental study on secondary processing of sulfur concentrate containing arsenic

Weiping Yan

Abstract

Targeted at pyrite concentrate containing arsenic,improvement on mineral processing technology can gain high-quality sulfur concentrate.A small-scaled closed-circuit test in the lab obtains pyrite concentrate with 49.21 % sulfur,0.104 % arsenic,1.03 g/t gold,sulfur recovery of 92.42 % and gold recovery of 93.13 %.The problem in general utilization of iron-sulfur double resources in pyrite can be fundamentally solved.
