对内蒙古某全泥氰化尾渣进行了强化浮选试验研究。其结果表明：采用硫酸作为调整剂（矿浆pH值5．5）、WH－1作为活化剂、丁基黄药＋丁铵黑药作为捕收剂，经一次粗选、二次精选、二次扫选浮选流程，可获得铜品位5．67％、回收率85．37％，铅品位5．31％、回收率64．90％，锌品位10．95％、回收率82．66％的混合精矿，主要目的矿物均获得较好的富集，为后续铜、铅、锌、硫的浮选分离创造了有利的条件。
Experimental research on Mineral processing was carried out on all-sliming cyanidation tailings from Inner Mongolia.The results showed that mixed concentrates were obtained with copper grade of 5.67%,lead grade of 5.31%,zinc grade of 10.95%,copper,lead and zinc recoveries were 85.37 %,64.90%and 82.66%respective-ly,by flotation using WH-1 as regulator,butyl xanthate and aerofloat as collector,through the flowsheet of once roug-hing,twice cleaning and twice scavenging.The main target mineral was better enriched,and favorable conditions are created for the copper,lead,zinc flotation separation.
