摘要:
为解决四川某金矿选厂对该地区金矿回收率较低的问题,对该金矿进行了全面的矿石性质分析研究,并根据矿石性质的特点研究了回收该矿石中有用矿物的最佳工艺流程方案,并进行了多方案选矿对比试验.通过柱浸试验、浮选试验、重选试验、全泥氰化浸出试验的选金工艺方案对比试验结果表明:该矿可浸性很好,浸出试验金浸出率大于97%,重选、浮选回收率较低,最终确定了氰化浸出工艺流程.该工艺流程简单,可操作性强,对该地区的金矿回收具有指导作用.
Abstract:
To solve the problem of low recovery rate of gold mine in a gold mine selection plant in Sichuan, a comprehensive analysis of ore properties is carried out for the gold deposit According to the characteristics of ore properties, the optimum process scheme for recovering useful minerals in the ore was studied, and the comparison test of multi scheme mineral processing was carried out. Through the column leaching test, floatation test, reelection test and full mud cyanide leaching test, the comparison test results show that the ore is very impregnable, the leaching rate of the leaching test is more than 97%, and the recovery rate of the flotation and gravity are low. The process is simple and easy to operate, and has a guiding role in the recovery of gold deposits in this area.
