摘要
安徽某铜铅锌多金属硫化矿属复杂难选多金属硫化矿,铜铅锌矿物嵌布关系复杂,各矿物之间致密共生,粒度极为不均,综合回收难度大.为提高资源整体综合利用率,针对该矿石性质以Z-200为铜捕收剂,25#黑药为铅捕收剂,丁基黄药为锌硫捕收剂,采用铜铅锌硫依次优先浮选工艺流程,在原矿含铜0.58%、铅0.57%、锌2.50%、硫5.39%的条件下,获得了铜精矿Cu品位18.83%、回收率76.33%,铅精矿Pb品位45.83%、回收率 68.58%,锌精矿Zn品位50.25%、回收率87.44%,硫精矿S含量40.89%、回收率44.64%的实验室指标.研究结果为下一步工业化生产提供了指导依据.
Abstract
A copper-lead-zinc polymetallic sulfide ore in Anhui Province is a complex refractory polymetallic sulfide ore.The dissemination relationship of copper-lead-zinc minerals is complex,the miner-als are densely symbiotic,the particle size is extremely uneven,and the comprehensive recovery is difficult.In order to improve the overall comprehensive utilization rate of resources,according to the properties of the ore,Z-200 was used as copper collector,25#aerofloat was used as lead collector,butyl xanthate was used as zinc-sulfur collector,and copper-lead-zinc-sulfur preferential flotation process was adopted.Under the condition of 0.58%copper,0.57%lead,2.50%zinc and 5.39%sulfur in the raw ore,the copper concen-trate with Cu grade of 18.83%and recovery of 76.33%,the lead concentrate with Pb grade of 45.83%and re-covery of 68.58%,the zinc concentrate with Zn grade of 50.25%and recovery of 87.44%,and sulfur concen-trate with S content of 40.89%and recovery rate of 44.64%were obtained by the laboratory experiment.The results could provide guidance for the next industrial production.
