摘要
江西某选厂钨细泥脱硫后矿样含WO30.25%,主要以黑钨矿存在,黑钨相占82.10%,其次为白钨矿,白钨相占16.72%。针对细泥性质和生产流程现状,在实验室工艺研究基础上,确定采用磁-重选联合工艺流程对现场工艺进行改造,其中中磁选设备为SLon高梯度磁选机,重选设备采用离心选矿机,通过现场调试后正常运转,可获得钨精矿含WO330.26%,回收率为54.35%,对钨资源的综合回收利用提供一定的技术参考依据。
After desulfurization the tungsten fine mud contains 0.25% of WO3 ,which mainly exists in the form of black tungsten,accounting for 82.10%, and then scheelite, about 16.72%. In allusion to the current production process of fine mud in a jiangxi tungsten mines, the combined technological process of magnetic separation--gravity separation was adopted to modify the current process on the basis of laboratory technology research. When the SLon gradient magnetic separator and the centrifugal concentrator were adopted, through debugging for the normal opera- tion ,the tungsten concentrate with the grade of 30.26% and the recovery of 54.35% could be obtained,which pro- rides some technical reference for comprehensive recovery of tungsten resources.
