摘要
针对某多金属硫化矿中铜铅锌矿物共生关系密切和嵌布粒度细的特性,采用铜铅混合浮选-铜铅精矿再磨-铜铅分离-混浮尾矿选锌的浮选流程进行了系统的工艺条件试验,成功地实现了铜铅锌的分选,获得了铜品位和铜回收率分别为21.05%和86.71%的铜精矿、铅品位和铅回收率分别为63.94%和79.98%的铅精矿及锌品位和锌回收率分别为55.96%和84.50%的锌精矿,为合理开发该矿石资源提供了试验依据。
In light of the characteristics of copper-lead-zinc close intergrowth and fine dissemination size of a multi-metallic sulphide ore, a flotation flowsheet consisting of Cu-Pb bulk flotation-regrinding and reflotation of Cu-Pb rougher concentrate-Znic flotation was adopted and tested. Based on the systemic condition tests, the separation of copper from lead and zinc was realized successfully. The copper concentrate with Cu grade of 21.05% and 86.71%recovery,lead concentrate with Pb grade of 63.94% and 851 53% recovery,and zinc concentrate with Zn grade of 571 40 % and 85171 % recovery are obtained respectively. It provides an experimental basis for the reasonable recover of these mineral resources.
