新型捕收剂在陕西某混合铅锌矿石分选中的应用

The application on new regions in the separation of lead from zinc of a complex lead-zinc ore in Shanxi

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。

Abstract: 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.
