针对云南某铅锌浮选的高碱尾矿进行硫回收工艺流程研究.采用一次粗选三次精选两次扫选的流程回收硫,最终获得品位为53.13%,回收率为79.91%的硫精矿,并将砷含量降低到0.16%,成功实现了高碱尾矿没有酸中和的条件下硫的综合回收.%The study on sulfur recovery process flow is carried out for one lead-zinc tailings with high alkali and high arsenic by flotation in Yunnan.The sulfur recovery flow which one time rough concentration, three times concentration, two times scavenging is adopted, the obtained final sulfur concentrate has the 53.13% grade, 79.91% recovery rate, and the arsenic content was decreased to 0.16%, it successful realize the comprehensive recovery of sulfur without acid neutralization in the high alkali tailings.
