摘　　要：针对云南蒙自地区高砷含黄铁矿尾矿,利用石灰、高锰酸钾、腐殖酸钠和SN等不同抑制剂进行降砷试验,结果表明,在高碱条件下,新型有机抑制剂SN在不影响黄铁矿回收率情况下,实现了对毒砂的有效抑制。浮选试验结果表明,硫精矿中砷可从1.74%降至0.21%,硫精矿回收率可达85%以上。In order to utilize the sulfur tailings with high content of arsenic in Mengzi, Yunnan province, lime, potassium permanganate, sodium humate and new organic depressant SN had been used to separate arsenic and sulfur. The results indicated that SN can effectively depress arsenopyrite while had no effect on recovery of pyrite under the high alkalinity condition. The content of arsenic in sulfur concentrate can be down to 0.21% and the recovery of sulfur can be over 85% from the pyrite tailing of 1.74% As.
