提高“重选+全泥氰化”工艺流程选矿回收率的探索与应用

Exploration and Application of Improving Mineral Processing Recovery Rate of "Gravity Separation + Total Sludge Cyanidation" Process

针对广西某低品位多金属金矿选矿厂重选+全泥氰化工艺,排尾品位高,选矿回收率低的问题,通过对尾矿渣流程考察,尾矿渣物质组成特征,查明金矿物的流失特征、金属硫化物的特征,以此提出了提高选矿回收率有效途径,为企业获得更好的经济效益。

In view of the problems of high tailings discharging grade and low recovery rate in gravity separation and all-sliming cyanidation process of a low-grade polymetallic gold concentrator in Guangxi, through the investigation of tailings slag process, the material composition characteristics of tailings slag, the loss characteristics of gold minerals and the characteristics of metal sulfides are identified, and the effective ways to improve the recovery rate of ore dressing are put forward, so as to obtain better economic benefits for enterprises.
