含银铅低品位金矿石浮选试验研究及实践

Experimental research and practice of the flotation of low-grade gold ores containing silver and lead

为合理开发利用金矿资源,针对李子金矿蚀变岩型矿石性质,进行了小型浮选试验研究及生产实践。在获得的最佳条件基础上,通过对生产中工艺参数的优化,如增大捕收剂用量、适当降低矿石处理量、降低混合精矿产率、加入适量矿泥分散剂等,生产实践取得了较好的指标,金、银、铅的回收率分别为82.19%、84.61%、79.32%。

In order to properly exploit and utilize gold resources, the paper carried out lab flotation tests and their production practice according to the alteration rock ore property of Lizi Gold Mine. With the optimal conditions and op-timization of production parameters, such as increasing the dosage of collectors, reducing treatment amount of ores, re-ducing production rate of blended concentrates, adding dispersing agent of ore and mud, the production practice a-chieved good index. Gold,silver and lead recovery rates reach 82. 19 % ,84.61 % and 7 9 .3 2 % respectively.
