本文叙述了以钼精矿为原料,经加压浸出、溶液萃取纯化制取钼酸铵的全湿法新工艺。产品钼酸铵纯度符合国家标准和外贸出口标准,付产品硫酸钠为一品级,钼的总回收率达95%左右,生产成本低于目前国内水平。生产过程中无有害气体溢出。废液返回,尽力避免对环境造成污染。本工艺适合于处理标准钼精矿和低品位非标准钼精矿。 This paper describes a molybdenum concentrate as raw material, the pressure leaching, the extraction of purified ammonium molybdate preparation of the whole wet process. The purity of ammonium molybdate product conforms to the national standard and the export standard of export. The product sodium sulphate is a grade, the total molybdenum recovery rate is about 95%, and the production cost is lower than the current domestic level. No harmful gas spills during production. Waste liquid return, try to avoid pollution to the environment. The process is suitable for processing standard molybdenum concentrate and low-grade non-standard molybdenum concentrate.
