提高红透山铜矿选矿回收率的研究

摘要

Through the deep research on current flotation process and properties of crude ore from Hongtoushan, in line with the nature of useful mineral and the study of the relation of grinding fineness and metal recovery, the grinding fineness was found the key factor influencing Hongtoushan beneficiation. So the grinding craft was improved. Through the way of changing the size of grind medium, the grinding fineness was improved from 3% to 8%. The beneficiation index was improved.%通过对红透山选矿厂选矿工艺现状及原矿性质的深入研究,根据有用矿物嵌布特性和对磨矿细度与金属回收率关系的研究,确定影响红透山选矿指标提高的主要因素是磨矿细度,进而对磨矿工艺进行了改进,以改变二段磨矿介质尺寸的方式,使磨矿细度提高3％ ～8％,铜、锌、金、银回收率分别提高了0.71、1.57、1.20、1.33个百分点.
