钨矿重力选矿在最近几年来,不论流程或者生产指标方面都有很大的提高和改进。流程已逐渐地合理化,生产指标相应地提高了很多,但也还有一些需待研究解决的问题。本文就试验中的一些资料数据和个人的体会对钨矿重选过程中的有关问题进行探讨。重选前的准备作业重选前准备作业的好坏直接影响着重选的生产指标。我矿经过多次的流程查定工作,对重选前的破碎流程及手选废石流程进行改进(图1),改进后的最大优点是改变了其中一10公厘级别矿石的重复作业现象
In recent years, gravimetric beneficiation of tungsten ore has greatly improved and improved in terms of process or production index. The process has been gradually rationalized, the production index has been correspondingly improved a lot, but there are still some problems to be studied and solved. In this paper, some of the experimental data and personal experience on the re-election process of tungsten ore to discuss the issues. Before the re-election preparation work Before the re-election preparation work directly affects the quality of the re-election of production indicators. My mine has undergone several process ascertainments to improve the crushing process and the hand-picked waste rock process before the re-election (Figure 1). The greatest improvement has been the change in the repetitive operation of 10 mm of ore
