湿法冶金过程包含浸取;溶液净化及分离;纯金属或金属化合物的制备三部分。高压氢还原是溶液分离和纯金属或金属化合物制备的新方法。目前在工业上已采用此法生产铜、镍、钴粉和二氧化铀,但由于某些技术原因,采用高压氢还原生产钨、钼、钒的低价氧化物还没有发展到工业生产的水平。本文结合轻工业部株州钨、钼材料厂和中国科学院化工冶金所用高压氢还原直接从粗钼酸氨浸液中制取低价氧化钼的
Hydrometallurgical processes include leaching; solution purification and separation; pure metal or metal compound preparation of three parts. High pressure hydrogen reduction is a new approach to solution separation and the preparation of pure metals or metal compounds. At present, copper, nickel, cobalt powder and uranium dioxide have been produced industrially in this industry. However, for some technical reasons, the use of high-pressure hydrogen reduction to produce low-cost oxides of tungsten, molybdenum and vanadium has not yet reached the level of industrial production . In this paper, with the Ministry of Light Industry Zhuzhou tungsten and molybdenum materials plant and the Chinese Academy of Chemical Industry metallurgy using high-pressure hydrogen reduction directly from the crude molybdenum ammonia leachate Preparation of low-cost molybdenum oxide
