摘要
湖南某白钨矿矿物组成复杂,WO_3含量为0.34%,嵌布粒度细小,主要金属矿物为白钨矿,含有少量方铅矿、黄铁矿、闪锌矿等。试验采用预先脱硫—白钨粗选—加温精选的工艺流程最终获得含WO_3 61.80%、回收率75.93%的白钨精矿,取得了良好的选矿指标。
The scheeliteore in Hunan own s complex mineral composition and fine particle size distribution. The WO3content is 0.34% , the main metal mineral is mainly seheelite and a small amount of pyrite, galena, sphalerite etc. A scheelite concentrate with the grade of 61.80% WO3 and the recovery of 75. 93% rate can be obtained using the redesulfurization--scheelite roughing--heating selection processand achieved a good experiment index.
