介绍了采用酸盐分解—碱浸—水洗—净化—浓缩结晶等过程从氨浸渣中回收钼并生产钼酸钠的工艺。实验结果表明钼的浸取率达到 80 % ,制备的工业钼酸钠符合Q/JDC1 0 2— 2 0 0 2标准 ,满足国内外用户的要求
The process of recovering molybdenum from ammonia leach residue and producing sodium molybdate by using acid decomposition, alkali leaching, washing, purifying and concentration crystallization is introduced. The experimental results show that the leaching rate of molybdenum reaches 80%, and the prepared industrial sodium molybdate meets the Q / JDC1 0 2-2020 standard to meet the requirements of domestic and foreign users
