针对安徽某含金硫精矿砷含量较高（达 5.05%），无法销售的问题，进行了砷硫分离试
验。结果表明，以活性炭为脱药剂，石灰为pH值调整剂，ZJY-7为抑制剂，丁基黄药为捕收剂，
2# 油为起泡剂，优先浮选黄铁矿，浮选尾矿磨细至-0.074 mm占82.37%，经过1粗1扫磁选分离毒砂和磁黄铁
矿，获得了可销售的含硫 52.16%，含砷 0.48%，含金 1.86 g/t，硫回收率 14.32% 的硫精矿 1，含硫
35.81%，含砷0.63%，含金0.61g/t，硫回收率64.08%的硫铁精矿2和含砷16.46%，含金8.14 g/t，砷回收
率91.25%，金回收率80.22%的含金砷精矿，合计硫回收率78.40%。试验结果可为同类矿山处理高砷
含金硫精矿提供参考与借鉴。
Aiming at the problems that the arsenic content of a gold-bearing sulfur concentrate in An⁃
hui is too high (up to 5.05%) to be sold，an arsenic-sulfur separation test was carried out. The results show
that pyrite is preferentially floated with activated carbon as de-reagent，lime as pH regulator，ZJY-7 as in⁃
hibitor，butyl xanthate as collector and 2# oil as foaming agent. The flotation tailings were ground to -0.074
mm accounting for 82.37%. After one roughing and one scavenging magnetic separation of arsenopyrite and
pyrrhotite，a marketable sulfur concentrate with sulfur content of 52.16%，arsenic content of 0.48%，gold
content of 1.86 g / t，sulfur recovery rate of 14.32%，sulfur and iron concentrate with sulfur content of
35.81%，arsenic content of 0.63%，gold content of 0.61 g/t，sulfur recovery rate of 64.08%，and gold⁃
bearing arsenic concentrate with arsenic content of 16.46%，gold content of 8.14 g/t，arsenic recovery rate
of 91.25%，gold recovery rate of 80.22%，and total sulfur recovery rate of 78.40% were obtained. The test
results can provide reference for the treatment of high arsenic gold-bearing sulfur concentrate in similar
mines.
