综合回收复杂铅锌矿伴生铜资源浮选新工艺试验研究

Study on New Flotation Craft of Recovering Copper Resource Associated in Lead Zinc Sulphide Ore

文章从试样的工艺矿物学研究出发,在查明试样矿物组成、赋存状态和嵌镶关系的基础上,确定了优先浮选的实验方案。尔后进行了大量的条件试验以确定最佳的工艺流程和工艺参数,进行全流程闭路试验,取得了良好的分选指标后,再在工业上进行工业应用试验。其主要技术创新点有:采用高效捕收剂BP实现铜铅优先浮选;采用高效无毒组合抑制剂实现铜铅的有效分离;采用铜中矿集中旋流器分级再磨处理解决了铅的恶性循环和单体解离度低,有效地解决了铜铅分离的技术难题。该工艺的成功应用,为有效利用有限的不可再生伴生铜资源,提供了详实的技术依据。

Setting out from the craft mineralogy research of sample, the paper makes sure the experiment project of the preferential flotation on the basis of investigating the mineral sample composition and the relationship and Mosaic relation. Then after a great deal of conditional experiments to make sure the best craft process, the craft parameter is finished, and the closed circuit experiments obtained a good separating indicator. The main technological innovation is as follows： Adopting collector Bp was of high - effect to float copper; using no- toxic and combinatorial depressants to depress lead, the experiment was carried out effectively for separation of copper- lead; Adopting processing of copper middle to concentrate a cyclone classificating and a mill regrinding, it solved the vicious cycle of the lead and was of low dissociation. The successful application of technology refemences for the effective use of limited non- renewable resources associated with copper, provides a detailed technical.
