近年来,用于制取金属粉末的纯三氧化钨越来越多地用成分复杂的原料生产,生产中使用的既有贫矿也有二次原料。制取钨的湿法冶金工艺必须保证充分地以三氧化钨形式回收钨,而还要保证钨的高纯度。因此,湿法工艺的最重要的课题之一就是分离钨和钼,并获得付 In recent years, pure tungsten trioxide used for preparing metal powder is more and more used in the production of raw materials with complicated compositions, and the existing lean ore used in the production also has secondary raw materials. Preparation of tungsten hydrometallurgical process must ensure that the full recovery of tungsten as tungsten trioxide, but also to ensure the high purity of tungsten. Therefore, one of the most important topics in the wet process is the separation of tungsten and molybdenum, and the acquisition
