摘　　要：国外某含铋硫精矿铋品位为0.47%,根据含铋硫精矿化学组成、矿物组成及物相分析,作者采用磁性分析试验和条件试验,确定采用"磁浮"联合的工艺流程处理该矿石,并采用了石灰+水玻璃作硫抑制剂、硫酸铜作铋活化剂,自主研发的SAH作铋捕收剂,获得了铋品位为34.26%、回收率为80.06%的铋精矿,硫品位46.89%、回收率40.54%的硫精矿,硫品位31.67%、回收率58.45%、含铁53.29%的高铁硫精矿,客观有效地实现了矿石铋、硫资源的综合回收。The bismuth content of a bismuth sulfur concentrate abroad is 0.47%.According to the chemical composition, mineral composition and phase analysis, the author adopted magnetic analysis test and conditional test. The results show that bydealing with the sample by "magnetic-flotation" combination,and lime + sodium silicate as sulfur inhibitor, CuSO4 as bismuth activator, SAH as bismuth collector, we obtained a bismuth concentrate grade of 34.26% Bi at 80.06% recovery, a sulfur concentrate grade of 46.89% S at40.54% recovery, a high iron sulphur concentrate grade of 31.67% S at 58.45% recovery. Bismuth and sulfur resources can be effectively and comprehensively reclaimed.
