龙头山金矿选矿厂原矿品位、氰原品位问题探讨

Discussion on grades of raw ores and raw ores for cyanidation in ore-dressing plant of Longtoushan Gold Mine

针对贵港市金地矿业有限责任公司龙头山金矿选矿厂重选+氰化工艺流程因存在粗粒明金、矿样代表性差、部分金提前浸出,导致原矿品位、氰原品位实际值与理论值存在误差,金属难以平衡的问题。通过改进措施、选取合适的取样点,确定了一种较为合理的计算方法,使其实际值与理论值基本相符。

There are many defects in gravity separation -cyanidation process currently used in ore-dressing plant of Longtoushan Gold Mine, Guigang Jindi mining company, that are the presence of coarse-grained visible gold, poor representativeness of samples and early leached gold, making the actual value of the grades of raw ores and raw ores for cyanidation deviate from the theoretical one and resulting in the imbalance between metal. To deal with that, optimiza- tion measures are taken, proper sampling sites are selected and thus a fairly reasonable calculation method is obtained, making the actual value of the grades consistent with the theoretical one.
