摘　　要：采用硫砷依次优先浮选、再磁选的流程,在酸性条件下对某含砷高硫难处理金矿进行硫砷分离。通过闭路试验,得到了高质量的硫精矿和含金砷精矿,实现了硫砷的有效分离,提高了金的回收率。With the process of selective flotation sulfur and arsenic and then magnetic separation,the tests of sulfur-arsenic separation were carried on in acidic conditions for a refractory gold ore containing arsenic and high-sulfur.By close-circuit experiment,high-quality sulfur concentrate and arsenic concentrate containing gold were obtained respectively,and sulfur and arsenic were separated effectively.At the same time,the recovery of gold was improved.
