摘　　要：针对攀西地区某选钛浮选斜板沉砂采用常规“先浮硫再硫钴富集”工艺及常规药剂“丁基黄药+2#油”回收硫化物时,硫钴回收率低、不利于后续硫钴浮选分离等问题,采用“一粗两扫三精”浮选流程,并添加微细粒硫钴矿物高效辅助捕收剂EMC-50、起泡剂EMP-02和抑制剂EM515等进行了实验室优化研究。试验表明,添加新药剂后能获得产率2.00%、S品位36.37%、Co品位0.36%、S回收率83.53%的硫精矿,硫精矿的回收率较当前采用常规药剂的提高了3.21个百分点,单位硫精矿药剂成本降低111元/t。新药剂的使用将有利于提高攀西硫精矿的综合利用价值。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 re-agent,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.
