摘　　要：本文介绍了从焙烧钼精矿水洗制备七钼酸铵工艺试验,制备出了符合国家标准和日本客户要求的合格七钼酸铵。该工艺与国内传统的七钼酸铵制备工艺相比,缩短了工艺流程,改善了操作环境,减少了氨氮废水排放,降低了成本。In this paper, the technological test is introduced, from washing roasted molybdenum concentrate to pre-pare ammonium hepta molybdate which comes up to the national standard and the requirements of Japanese custom-ers.Compared with the traditional process of preparation of ammonium hepta molybdate, this technology test short-ens the process, improves the operating environment, reduces the ammonia nitrogen wastewater discharge and the cost of production.
