Abstract

Abstract

In the case of sanding of a titanium flotation inclined plate in Panxi area, the conventional process of “first floating sulfur and then enriching cobalt sulphide” and the recovery of sulphides with the conventional reagent “Butyl xanthate +2^# oil” were adopted, the low recovery of cobalt sulphide is unfavorable to the subsequent flotation separation of cobalt sulphide, the flotation process of “one roughing, two sweeping and three refining” was optimized by adding high efficient auxiliary collector EMC-50, foaming agent EMP-02 and inhibitor EM515.The results showed that sulfur concentrate with yield of 2.00% , S grade of 36.37% , Co grade of 0.36% and S recovery of 83.53% could be obtained by adding new reagent, the recovery of pyrite concentrate is 3.21% higher than that of conventional reagent, and the reagent cost per unit pyrite concentrate is 111 yuan/t lower. The use of new reagents will be beneficial to improve the comprehensive utilization value of Panxi pyrite concentrate.
