摘要
为解决某锡多金属硫化矿选厂选铅锌尾矿中硫砷的流失问题,对该尾矿进行了综合回收硫砷的选矿试验。试验结果表明:采用弱磁选—硫砷混合浮选—硫砷分离浮选流程,并在硫砷分离浮选时采用砷的高效抑制剂Y-As,可获得硫品位为43.14%、含砷0.56%、硫回收率为64.12%的综合硫精矿和砷品位为12.08%、砷回收率为86.79%的砷精矿,实现了硫、砷的有效分离和回收。
In order to prevent the loss of sulfur and arsenic from the Pb-Zn tailings of Tin poly-metallic sulfide ores,the beneficiation tests on this tailing were carried out to comprehensively recover sulfur and arsenic.The results showed that by the process of low intensity magnetic separation-bulk flotation of sulfur and arsenic-the flotation separation of sulfur-arsenic,sulfur concentrate with S grade of 43.14%,Arsenic content of 0.56% and S recovery of 64.12%,and arsenic concentrate with arsenic grade of 12.08% and arsenic recovery of 86.79% were obtained with the high-efficient depressant Y-As during the flotation separation of sulfur and arsenic.This method can achieve the effective separation and recovery of sulfur and arsenic.
