钨精矿通常采用酸法或碱法处理。在碱法处理工艺中,钨转变为钨酸钠,含钨矿石中的硅、磷、氟和锡等杂质也被碱分解进入钨溶液中。这些杂质成分应尽可能彻底的从钨溶液中除去,因为它们会妨碍后续工序的处理。例如:硅会影响钨溶液的溶剂萃取,磷和氟会干扰杂质铜的除去,均污杂最终钨产品。 Tungsten concentrates are usually treated with acid or alkali. In the alkaline treatment process, tungsten is converted to sodium tungstate, and silicon, phosphorus, fluorine, and tin in tungsten-bearing ores are also decomposed into the tungsten solution by alkali. These impurity components should be removed from the tungsten solution as thoroughly as possible because they prevent subsequent processing. For example: Silicon will affect the solvent extraction of tungsten solution, phosphorus and fluorine will interfere with the removal of copper impurities, are contaminated with the final tungsten products.
