摘要：
Phosphorus removal slag from tungsten smelting was an important recycling resource of Mo and ＷO3. A method of thermal pressure leaching with sodium carbonate and sodium hydroxide was proposed to leach Mo and ＷO3 from phosphorus removal slag from tungsten smelting. The results show that the synergistic leaching with sodium carbonate and sodium hydroxide,the leaching rate of Mo and ＷO3 was raised substantially. Effect of leaching agent dosage of sodium carbonate and sodium hydroxide,leaching time,leaching temperature,leaching liｑuid to solid rate,leaching stirring speed on the leaching rate of Mo and ＷO3 were investigated. The optimum processes conditions are as follow:250％ theoretical dosage of sodium carbonate sodium carbonate,15％ theoretical dosage of sodium hydroxide,leaching time 2 h,leaching temperature 188 ℃,leaching liｑuid to solid rate 3 ∶ 1,leaching stirring speed 80 r / min,the leaching rate of Mo and ＷO3 were reached 99. 19％,99. 11％,re-spectively. Ｕnder the same optimum processes conditions,an industrial leaching test of phosphorus removal slag was proposed,the leaching rate of Mo and ＷO3 were higher than 98. 50％,98. 40％,respectively,and the content of Mo and ＷO3 on leaching slag were less than 0. 16％, 0. 20％,respectively. © 2023 Cailiao Daobaoshe/ Materials Review.
