本发明公开种钨冶炼除钼渣的处理方法，包括：将除钼渣和氨水加入到高压釜中，控制定的氧分压和温度进行浸出反应；反应完成后，将浸出液流过装有强碱性阴离子交换树脂的离子交换柱，得到含铜的交后液经蒸发浓缩后返回钨冶炼的除钼工序；用氯化铵和氨水的混合溶液解吸钼和钨，同时使树脂得以再生，所得解吸液经钼钨分离后用于制取相应的钼产品和钨产品。本方法流程短，操作简单，资源回收率高，生产成本低，减少了废水和SO烟气的排放，具有显著的经济效益和生态效益。 The invention discloses a treatment method for molybdenum removing slag for tungsten smelting. The treatment method includes the steps that the molybdenum removing slag and ammonium hydroxide are added into a high-pressure kettle, and certain oxygen partial pressure and a certain temperature are controlled for conducting a leaching reaction; after the reaction is completed, a leaching agent flows through an ion exchange column containing strong-basicity anion exchange resin, obtained exchange liquid containing copper is evaporated and condensed and then returns to the molybdenum removing process of tungsten smelting; and molybdenum and tungsten are desorbed through a mixed solution of ammonium chloride and ammonium hydroxide, meanwhile the resin can be regenerated, and the desorbing solution is
