金属需要量的增长,促进了对矿物原料的综合利用和合理采用改进的处理方法以提高金属回收率。解决上述问题的一个步骤是处理贫的、不合格的原料,产出合乎工作过程较高要求的人造产品。苏打熔炼白钨或黑钨法对处理钨钼原料是一个有前途的方法,该法处理过程中发生熔析现象,由此,钨在一般情况下形成单独的一层钨盐熔融物。在钨酸盐精炼时,大部伴生杂质(硅、铁、铝、钙等)部分或全部富集到渣相(硅酸盐产品)。
The increase in metal requirements has facilitated the comprehensive utilization of mineral raw materials and the rational use of improved processing methods to increase metal recovery. One of the steps to solve the above problems is to deal with poor and unqualified raw materials and produce man-made products that meet the higher requirements of the work process. Soda smelting The scheelite or black tungsten process is a promising method for the processing of tungsten and molybdenum starting materials. The melting process occurs during this process, whereby the tungsten forms a single layer of tungsten salt melt under normal circumstances. In tungstate refining, most of the accompanying impurities (silicon, iron, aluminum, calcium, etc.) are partially or fully enriched to the slag phase (silicate product).
