含金黄铁矿纯矿物制备

The preparation of pure auriferous pyrite

本试验采用重选、磁选、电选三种方法制备含金黄铁矿纯矿物。通过适当地调节各种选别方法的操作条件,物料分三个级别分离提纯含金黄铁矿纯矿物。分选结果,不仅使单矿物的纯度符合试验研究要求,而且保持了纯矿物的原矿性质。

According to the study in this paper, the pure auriferous pyrite can be prepared by means of gravity or magnetic or electric concentration. Through modification of operating condition, there are three classes of pure auriferous pyrite liberated from the head of mill. For monomincrals, it shows that not only its purity suit the requirement, but the original property of the pure mineral closely remains unchanged.
