| 摘 要： | 白钨矿精矿中黑钨矿的物相分析,与黑钨矿中少量白钨矿的物相分析一样,都是由于两者的含量相差过于悬殊,很艰找到合适的选择性溶剂和条件,得到较为满意的分析结果,所以至今仍为国内外尚未过关的课题.本文应用新的选择性溶剂-结晶氯化铝,它比以往使用的那一种选择性溶剂对白钨矿的溶出率要大,采取适当措施后黑钨矿的溶出率可以降低得很小,并且对钨矿中的一些常见共生的含钙矿物能同时全部除去,在此基础上测定残渣中的钨(黑钨矿和残剩少量白钨矿的和)和钙(白钨矿的钙),钙的含量按CaWO_4固定组成换算成白钨矿的钨,差减即得黑钨矿的钨.

| Abstract: | The phase analysis of wolframite in the scheelite concentrate is a difficult problem.In this paper,a high crystalline aluminium chloride solution is used to dissolve the scheelite and other calcium-contained minerals.The tungsten and the calcium in the residue are determined By the formula of CaWO4,the content of calcium can be converted into tungsten of the scheelite in the residue.The difference of the tungsten in the residue and the tungsten converted from calcium is wolframite. |
