对胶东地区低品位氰化尾渣中铜铅锌综合回收利用进行了试验研究，采用“优先选铅后铜锌混浮—分离”工艺，以新药剂YY-1为锌抑制剂进行了闭路试验，可得到铅精矿中铅品位24.73%、铅回收率75.65%，铜精矿中铜品位16.77%、铜回收率60.56%，锌精矿中锌品位43.91%、锌回收率68.31%的良好技术指标。
Experimental research on comprehensive recovery of copper,lead and zinc from low grade cyanide tail-ings in Jiaodong region is carried out,a process of preferential separation of lead before bulk flotation,and then separa-tion,of copper and zinc is adopted.With the new depressor YY-1 in the closed circuit,a lead grade of lead concen-trates of 24.73 %is obtained with lead recovery rate of 75.65 %,a copper grade of copper concentrates of 16.77%with copper recovery rate of 60.56 %,and a zinc grade of zinc concentrates of 43.91 % with zinc recovery rate of 68.31 %,representing a good technical index.
