| 摘 要： | 针对长坡选矿厂锌浮选尾矿硫砷矿物相互伴生且部分矿物未单体解离的特点,考虑全浮硫化矿,全浮精矿再硫砷分离的原则流程,在硫砷浮选分离过程中采用过氧化氢与腐殖酸钠1∶1药剂组合抑制砷矿物,在用量仅为900g/t条件下,硫精矿品位达到44.86%,回收率达到87.88%,硫精矿中砷含量可降低到1%以下。

Experimental study on the separation of pyrite and arsenopyrite for the tailings of zinc sulfides flotation in Changpo plant |

| Abstract: | In Changpo plant,the arsenic-sulfur minerals were associated with each other and part minerals were not yet liberated in the tailings of zinc sulfides flotation.According to this problem,a new flowsheet was proposed that bulk flotation was firstly adopted,and then the sulfides concentrate was processed for the separation of arsenic-sulfur minerals.In this experiment,a combined agent of hydrogen peroxide and sodium humate(1:1) was used as an arsenic depressant.The results showed when the depressant dosage was 900g/t,desirable indexes could be achieved that the grade and recovery of sulfide concentrate were respectively 44.86% and 87.88%,and the arsenic content could be reduced to below 1%. |
