摘要
对复杂的某混合铅锌矿进行了铅锌分离研究。分析了矿石的化学组成和铅锌物相,查明了矿石中铅、锌的种类及粒度嵌布特征。采用硫化铅、氧化铅、硫化锌、氧化锌依次单独浮选回收方案,并在试验中使用选择性较强的铅捕收剂BS-1和氧化锌锌捕收剂HY-57,最终获得铅品位51.00%、回收率72.48%、含锌2.77%的硫化铅精矿;铅品位41.65%、回收率18.79%、含锌7.31%的氧化铅精矿以及锌品位51.00%、回收率86.18%、含铅1.12%的硫化锌精矿;锌品位6.82%、回收率8.76%、含铅0.49%的氧化锌精矿,选矿指标较好,有效地解决了该混合铅锌矿石的分选问题。
Study was made on the separation of lead and zinc in a complex lead-zinc ore. The chemical composition and lead-zinc phases of the ore were analyzed and the kinds of lead, zinc and their size disseminating characters were indentified. A preferential flotation flowsheetwas adop ted, As a result, a lead sulfide concentrate with 51. 00%lead grade, 72. 48% recovery and 2. 77% zinc content, a lead oxide concentrate with 41.65% lead grade, 18.79 %recovery and 7. 31%zinc content;a zinc sulfide concentrate with 51.00% lead grade,86.18% recovery and 1. 12% lead content,a zinc oxide concentrate with 6. 82% lead grade,8.76% recovery and 0. 49% lead content. Thus,the complex lead-zinc ore is effectively realized.
