摘要
针对某富含砷、锑的难选银铜铅锌多金属矿石,应用高效选铜药剂BK905B和高效选铅药剂BK906,采用适合该矿石性质的顺序优先浮选工艺,产出了供湿法冶金处理的铜精矿和单独的铅精矿及锌精矿。全流程闭路试验结果为:铜回收率为93 09%,铅和锌的总回收率分别为89 46%和92 08%。铜精矿和铅精矿中的金、银总回收率分别为57 44%、92 88%。该方案工艺简单,操作方便。
BK905B,which is a selective copper collector,and BK906,which is a selective lead collector, are adopted in a selective flotation flowsheet for treating a refractory copper-lead-zinc-silver ore.A copper concentrate,which can be treated by hydrometallurgy ways,a lead concentrate and a zinc concentrate are obtained separately.93.09 percent of Cu,89.46 percent of Pb and 92.08 percent of Zn are recovered.The total recovery of Au in copper and lead concentrates is 57.44%,and it is 92.88% for Ag.The flowsheet is simple and easy for operation.
