我国黑钨矿床,大多数由于矿床赋存、矿化特性开采条件及管理等诸因素关系,致使出窿矿石混有大量围岩,为了经济地进行选矿,必须在磨选前采用有效方法,预先丢弃一部分废石和杂物,同时回收块钨及伴生有用矿物。尤其在今天工业生产要求提高质量、降低消耗、增加效益的形势下,加强矿石的预选,更显得十分重要。
Most wolframite deposits in our country are due to deposit mineralization, mining conditions and management and other factors, resulting in a large number of outlying ore mixed with rock, in order to carry out beneficiation beneficiation, the grinding method before the effective method must be used in advance Discard a portion of the waste rock and debris while recovering the tungsten and accompanying useful minerals. Especially in today’s industrial production requirements to improve quality, reduce consumption and increase efficiency, it is even more important to strengthen ore pre-selection.
