文章阐述了现有钼酸铵生产工艺的特点及不足，进行大量的小型试验研究，提出了优化工艺，确定了新工艺的较佳工艺条件。利用新工艺处理钼焙砂，一方面可大大降低焙砂中的杂质含量，降低了硫化铵的单耗，每吨钼酸铵硫化铵单耗由0.025t降至0.01t以下，且有效地提高钼酸铵产品品质和纯度，另一方面实现了钼铼有效分离，并为铼金属综合回收提供了有利条件。

The article expounds the characteristics and disadvantages of existing ammonium molybdate production technology. After a large number of small experimental studies, the optimization process is proposed, a better technological conditions of the new technol-ogy is determined. After using the new technology to process molybdenum calcine, on the one hand, the impurity content in the calcine can be greatly reduced, the unit consumption of ammonium sulfide is reduced, ammonium molybdate ammonium sulfide unit consump-tion per ton by below 0. 025t to 0. 01t, and the product quality and purity of ammonium molybdate are effectively improved. On the oth-er hand, the effective separation of molybdenum rhenium is achieved, the rhenium metal comprehensive recovery is achieved and favor-able conditions are provided.
