会理锌矿长期因矿石性质多变、矿物组成复杂、锌铅含量比值大、伴生银嵌布粒度细、浮选磨矿细度又未达到设计要求 ,致使铅锌分离困难 ,生产指标难以提高。采用选择性较好的捕收剂及对锌矿物有强烈抑制作用的组合抑制剂 ,并优化工艺条件 ,解决了铅锌分离困难的问题 ,达到了提高铅锌精矿质量与铅锌精矿中主金属回收率的目的。
Due to the changeable nature of minerals, the composition of mineral composition is complicated, the ratio of zinc to lead is large, the fineness of silver cloth is fine, and the fineness of flotation grinding does not meet the design requirements, making the separation of lead and zinc difficult and the production index difficult to be improved . The use of better selective collector and zinc inhibitor has a strong inhibitory effect on the combination of inhibitors, and optimize the process conditions, to solve the problem of lead and zinc separation difficult to achieve to improve the quality of lead and zinc concentrate and lead-zinc concentrate The purpose of the main metal recovery rate.
