我矿矿石性质比较复杂,加以钨矿物性脆,在选矿过程中产生了部分含钨低、含杂质高、粒度细的矿泥。以往采用选矿焙烧方法回收其中一部分钨产品,并掺和到精矿中出厂。其余部分又采用简单的选矿方法回收,因而大部分流失于尾矿中,回收率很 I am more complicated nature of ore ore, with tungsten mineral brittle, in the beneficiation process has resulted in part of the low tungsten, containing impurities, fine grain size of the mud. In the past, beneficiation roasting method was used to recover some of the tungsten products, and blended into the concentrate in the factory. The remaining part of the simple beneficiation method used again, so most of the loss in the tailings, the recovery rate is very
