湘东钨矿矿石性质比较复杂,加之钨矿石性脆,以致在精选过程中产生了一部分含钨量较低、含杂质很高、粒度极细的矿泥。这种矿泥用选矿工艺来处理收效不大。为了合理地综合利用这部分有用资源,使其变废为宝,化害为利,该矿采用烧碱浸出法的水冶工艺来处理这种矿泥以生产三氧化钨,收到较好的效果。该工艺主要过程是: 矿泥→烧碱浸出→浓缩结晶→溶解净化→白钨合成→酸分解→
The ore quality of the Xiangdong tungsten ore is rather complicated, and the brittleness of the tungsten ore results in a part of the slime containing a lower amount of tungsten, a very high content of impurities and a very fine grain size in the selection process. This mineral processing technology to deal with the ineffective. In order to rationally make full use of this part of the useful resources, make it turning waste into treasure, harm for the benefit, the mine smelting caustic leaching method to deal with this sludge to produce tungsten trioxide, received good results . The main process of the process is: leaching of slime → caustic soda → concentrated crystallization → dissolution and purification → synthesis of white tungsten → acid decomposition →
