随着钨原矿品位逐步下降,矿石日趋难选,而国内外用户对钨精矿质量的要求越来越高。因此,精矿质量与回收率之间的矛盾日益突出,其关键是如何处理品位低,杂质含量高,粒度细的难选钨中矿,这是当前钨选、冶过程中急待解决的一个重要课题。在提高钨精矿产品质量过程中,将随之带 With the gradual decline in the grade of tungsten ore, ore increasingly difficult choice, and users at home and abroad on the quality of tungsten concentrates higher and higher. Therefore, the contradiction between concentrate quality and recovery rate has become increasingly prominent, the key is how to deal with low grade, high impurity content, fine grain size of refractory tungsten ore, which is the current tungsten election, smelting process an urgent solution important topic. In the process of improving the quality of tungsten concentrates, it will be brought along
