高杂质钨粉矿的净化处理实验研究

Experiment and Research on Purification of High-Impurity Tungsten Powder

对富含磷、硫、砷、铅、锡、铋的复杂结构的低品位钨矿粉进行火法还原净化除杂处理,得到了能用于钨铁合金冶炼使用的合格富钨渣和铋铅锡合金副产品。

For low grade tungsten fine-ore containing phosphorous,sulfur,arsenic,lead,tin and bismuth,pyrometallurgical reduction-purification process is used for removing impurities.With this process,the qualified high-tungsten slag suitable for making tungsten-iron alloy,and by-products of bismuth,lead,tin alloy are produced.
