According to the types of tungsten concentrates used and the impurities contained in them, the following processes can be used to produce secondary ammonium tungstate:1. High-pressure alkali boiling (caustic soda)- ion exchange - evaporation crystallization method of black tungsten concentrate;2. High-pressure alkali boiling (caustic soda)- solvent extraction - evaporation crystallization method for black tungsten concentrate;3. Scheelite concentrate soda boiling - ion exchange - evaporation crystallization method;4. Scheelite concentrate soda boiling solvent extraction evaporation crystallization method;5. Pressure boiling - ion exchange - evaporative crystallization method of scheelite concentrate with caustic soda and fluorine salt;6. Pressure boiling, solvent extraction and evaporative crystallization of scheite concentrate with caustic soda and fluorine salt;7. Hydrochloric decomposition - ammonia dissolution - evaporation crystallization method of scheelite concentrate;
