摘要
福建某钨钼矿矿石中有用矿物以辉钼矿、黑钨矿为主,并伴生有黄铁矿。为了给该矿产资源的开发利用提供依据,对其进行了选矿试验研究。试验经比较,采用优先浮钼—浮钼尾矿浮硫—重选回收黑钨矿的工艺流程,获得了含钼51.31%,回收率为80.77%的钼精矿,含钨63.80%,回收率为68.31%的钨精矿以及含硫41.54%,回收率为97.67%的硫精矿,使矿石中的有价元素得到了较好的综合回收。
A tungsten and monlybedenum ore from Fujian contains mainly molybednite and wolframite as valuable minerals that are associated with pyrite. Beneficiation tests were made on this ore to provide a basis for its exploitation and utilization. The process consisting of preferential molybdnium flotation, sulfur flotation from the tailings of molybenium flotation and wolframite recovery by gravity separation was finally adopted through comparative tests, which obtained a molybedenium concentrate grading 80.77% at a recovery of 51.31%, tungsten concentrate grading 63.80% at a recovery of 68.31% and a sulfur concentrate grading 41.54% at a recovery of 97.67%, achieving a good comprehensive recovery of the valuable elements of the ore.
