中文摘要: 对云南某地铅锌银多金属硫化矿进行浮选试验研究。原矿入选品位Pb 2.98%、Zn 3.92%、Ag 33.5g/t。采用铅硫混浮—铅硫分离—尾矿浮锌的工艺流程,闭路试验获得了铅精矿产率4.46%、Pb 52.29%,含Zn 4.34%,铅回收率84.53%;锌精矿产率6.20%、Zn 54.57%,含Pb 0.78%,锌回收率85.27%;富集在铅精矿中Ag 211g/t、银回收率28.38%的技术指标。
Abstract:A Flotation test of a lead-zinc-silver polymetallic sulfide ore from Yunnan was studied.The ore contains Pb 2.98%, Zn 3.92% and Ag 33.5g/t. Lead-sulphur bulk flotation—lead-sulphur separation—tailings choose zinc technical processing flowsheet is adopted. The closed-circuit test showed that lead concentrate yield was 4.46%, Pb 52.29%, Zn 4.34% and lead recovery was 84.53%;Zinc concentrate yield was 6.20%, Zn 54.57%, Pb 0.78%, and zinc recovery was 85.27%. Silver content in the lead concentrate reaches 211g/t and silver recovery was 28.38%.
