摘　　要：对锑品位24.58%、金品位76.92 g/t、硫含量14.46%的俄罗斯某高硫锑金混合精矿进行了降硫提质试验研究,采用新型捕收剂CJ-201和抑制剂CJ-5S进行闭路浮选,获得的锑精矿中锑和金品位分别为42.26%和92.36 g/t,回收率分别达到了88.04%和62.18%,实现了从俄罗斯锑金混合精矿中分选出高锑低硫型锑金精矿产品。An experimental study was carried out for sulfur reduction and upgrading of a high-sulfur antimony-gold bulk concentrate from Russia with Sb grade of 24.58%, Au content of 76.92 g/t and S content of 14.46%. A closed-circuit flotation test was conducted using a new collector CJ-201 and a new depressant CJ-5S. The Sb and Au grades in the antimony concentrate attained respectively 42.26% and 92.36 g/t, with the corresponding recoveries of 88.04% and 62.18%. With this approach, a antimony-gold concentrate product with high content of antimony and low content of sulfur can be separated out from antimony-gold bulk concentrates collected in a Russian mine.
