摘　　要：湖南宝山难选铅锌矿,在生产过程中长期使用氰化钠作为锌硫矿物的抑制剂。通过实验室试验,采用环保高效组合药剂"Tj+硫化钠+硫酸锌+亚硫酸钠",实现了铅锌硫浮选取消使用氰化钠的目标,获得良好的选矿指标。为了使试验研究成果在生产中得到推广应用,在宝山铅锌矿进行了工业试验。通过对工业生产的调试以及3个月的稳定生产,工业试验结果表明,无氰铅锌清洁选矿技术可以有效地在生产中得到应用和推广,实现难选铅锌矿无氰铅锌分离清洁生产,全面提高铅、锌、金、银选矿回收率。Sodium cyanide was used as the inhibitor of zinc and sulfide minerals for a long term in the beneficiation process of the refractory lead-zinc ore in Baoshan.The laboratory test result showed that,an environmental and efficient combination inhibitor of ＂Tj Sodium sulfide zinc sulfate sodium sulfite＂ can replace sodium cyanide,and good beneficiation indicators can be obtained.For the extension and application of the research achievement in production,the industrial test was carried out for the lead-zinc ore in Baoshan.The result indicated that non-sodium cyanide technology can effectively promote the production index,improve the lead,zinc,gold and silver recovery rate.
