摘要:

内蒙古某铅锌银多金属矿石中矿物种类繁多,共生关系复杂,针对这一矿石性质,开展了优先选铅再选锌的浮选工艺流程。在铅浮选过程中,引入新型捕收剂HB-600替代部分乙硫氮,并采用一次粗选两次扫选三次精选的选别流程;在锌浮选过程中,使用新型捕收剂HB-369,并采用一次粗选三次扫选三次精选的选别流程。现场工业调试试验结果表明:铅精矿的铅品位为57.21 %、铅回收率94.48 %,银品位为1 688.3 g/t、银回收率为88.52 %,锌精矿锌品位为48.07 %、锌回收率为88.25 %。研究结果为铅锌银多金属矿选矿工艺的优化提供了依据。

Abstract:

A flotation process was developed that prioritizes lead selection followed by zinc selection,taking into account the perse ore types and complex symbiotic relationships.In the lead flotation process,the new collector HB-600 as a replacement for some Sodium diethyldithiocarbamate was introduced and the separation process of once roughing-twice scavenging-three times cleaning was used;while in the flotation of lead and zinc,the new collector HB-369,the separation process of once roughing-three times scavenging-three times cleaning was used.Field industrial commissioning results show that the processes can obtain a lead concentrate with a grade of 57.21 % and a recovery rate of 94.48 %,as well as a silver grade of 1 688.3 g/t and a silver recovery rate of 88.52 %;a zinc concentrate with a grade of 48.07 % and a recovery rate of 88.25 %.These results provide valuable references for optimizing the mineral processing technology of lead-zinc-silver polymetallic ores.
