瑶岗仙钨矿精选工段的难选高锡钨细泥,粒度细,含锡较高,钨锡分离困难,长期堆存未能合理利用。该矿委托我们对此种钨细泥进行高梯度磁选的研究。要求达到钨精矿含锡0.6％左右,WO_3回收率70％左右。 1981年6月完成实验室型试验。试验指标为:当原矿含WO_235.48％、含锡4.05％时,一次粗选所得钨精矿含WO_364.04％,含锡0.32％,WO_3回收率90.25％。
Yao Gangxian tungsten ore refractory selected section of the high tin tungsten fine mud, fine grain size, high tin content, tungsten and tin separation difficulties, long-term stockpiling failed to rational use. The mine commissioned us to conduct a high gradient magnetic separation of tungsten fine mud. Requirements of tungsten concentrate containing about 0.6% tin, WO_3 recovery rate of about 70%. June 1981 to complete the laboratory test. The test index is as follows: When the raw ore contains WO235.48% and contains 4.05% tin, the tungsten concentrate obtained from a rough separation contains WO_474.04%, tin 0.32% and WO_3 recovery 90.25%.
