Experimental Study on Recovery of Pyrite from Certain Lead-zinc Tailing

Publish Date: 01 December 2017

摘要: 某铅锌矿选硫尾矿中全年平均硫品位约为6%,研究结果表明损失在尾矿中的硫主要黄铁矿的形式存在,其解离度为66.55%.尾矿中+40μm粒级黄铁矿金属分布为56.51%,但其解离度只有45.8%.为使资源充分利用,并增加企业收入,对该铅锌矿选硫尾矿进行了实验研究.研究表明在设计的一次粗选,粗精矿再磨后两次精选,一次扫选浮选试验流程中,最终可获得硫品位为42.58%,回收率为60.12%的硫精矿.该硫精矿可与工业生产的高品质硫精矿混合从而提高精矿产量.

Abstract: The annual average grade of sulfur in certain Lead-zinc tailing is 6%.Research shows that the main form of sulfur is pyrite in the tailing with the degree of dissociation of 66.55%.The metal distribution of pyrite whose particle size is larger than 40 μm is 56.51%.But the degree of dissociation of this part of pyrite is just 45.8%.In order to make full use of resources and make profits for the enterprise,this kind of Lead-Zinc tailing was researched.The results showed that sulfur concentrate with sulfur grade of 42.58% and recovery of 60.12% was obtained through the process of one roughing two cleaning,and one scavenging.This sulfur concentrate can be mixed with industrial production of high quality sulphur concentrate to increase the concentrate production.
