矿物的解离是选矿的前提。我国的黑钨矿以粗粒嵌布为主,单体分离出现早,适宜用跳汰机及早回收。因此,合理控制碎矿产品粒度,不仅是改善磨矿作业的需要,而且是提高重选指标的关键。本文以瑶岗仙钨矿选矿厂的生产实践为例,探讨控制合理的碎矿产品粒度的意义和措施。一、碎矿和重选简况(一)矿石性质处理的矿石为石英脉型黑钨矿石。主要金属矿物按含量递减顺序排列,计有毒砂、黄铁矿、黑钨矿、锡石、 Mineral dissociation is the premise of mineral processing. Wollastonite in our country is mainly composed of coarse-grained cloth, with early appearance of monomer separation, suitable for early recovery with jig. Therefore, a reasonable control of the size of crushed ore products not only improves the demand for grinding operations, but also is the key to improving the re-election targets. This paper takes the production practice of Yao Gangxian tungsten ore dressing plant as an example to discuss the significance and measures of controlling the particle size of the crushed ore products. First, crushing and re-election profile (A) the nature of ore ore processing quartz vein type tungsten ore. The main metal minerals in descending order of content, arsenopyrite, pyrite, wolframite, cassiterite,
