摘要
随着黑钨矿资源的枯竭,白钨矿代替黑钨矿资源已逐渐成为未来钨冶金的发展趋势,简单有效的钨冶炼技术已成为众多学者研究的焦点。针对氟盐浸出白钨矿工艺,通过热力学计算,绘制了浸出溶液含氟0.10mol/L和0.12mol/L时各组分的平衡浓度对数图,并利用此图对氟盐浸出白钨矿工艺进行了热力学分析。
With the depletion of wolframite,scheelite concentrate substitute has become the developing trend of the future extractive metallurgy of tungsten.For the hydrometallurgical processing of scheelite concentrate by fluoride solution,the equlibrium concentration logarithm diagrams of every component is drawn according to thermodynamics calculation,under conditions of 0.10 mol/L and 0.12 mol/L fluoride concentration.Based on the logarithm diagram,the thermodynamic analysis is made of scheelite leaching by fluoride solution.
