摘要
以广西某多金属硫化铅锌矿为研究对象,针对其“锌高铅低”、铅锌分离困难的问题,采用新型高效抑制剂JFR-1,经一粗两精两扫铅锌混合浮选和一粗两精两扫铅锌分离,最终获得了Pb品位21.00%、回收率72.82%的铅精矿和Zn品位6.96%、回收率94.21%的锌硫化矿,尾矿中Pb、Zn品位及对应的回收率分别为0.04%、0.13%及10.85%、4.79%,实现了铅锌的富集和分离。
A kind of polymetallic lead-zinc sulfide ore in Guangxi was taken for experimental research.In view of its characteristics of high zinc and low lead,as well as difficulty in the separation between zinc and lead,a new type of efficient inhibitor JFR-1 was adopted in the experiment.It is shown that the lead-zinc sulfide ore was subjected to a lead-zinc bulk flotation,consisting of one roughing,two cleaning and two scavenging,followed by a separation of lead and zinc,consisting of one roughing,two cleaning and two scavenging,finally resulting in a lead concentrate grading 21.00% pb at 72.82% recovery,a zinc sulfide ore grading 6.96% Zn at 94.21% recovery,and a tailings grading 0.04% Pb and 0.13% Zn with a lead recovery of 10.85% and a zinc recovery of 4.79%.Thus,the enrichment and separation of lead and zinc can be actualized.
