一、前言目前世界上处理钨精矿,按黑钨精矿和白钨精矿分别采用碱法和酸法,低度白钨矿也有采用苏打压煮法。许多冶炼厂家只考虑钨的提取,为了自己冶炼方便,对钨精矿主成份含量要求高,杂质要求尽量少。因而钨精矿生产者在选矿过程中,为了满足用户对这些杂质的要求,必须采取很多措施,如将矿石粉碎到一定 I. Preface At present, the tungsten concentrates are treated in the world. Alkali and acid processes are adopted for the scheelite and scheelite concentrates, and the scheelite is also used for the smelting of scheelite. Many smelters only consider the extraction of tungsten, in order to facilitate their own smelting, tungsten content of the main ingredients of tungsten concentrate, impurity requirements as little as possible. Thus tungsten concentrates producers in the beneficiation process, in order to meet the user’s requirements for these impurities, must take many measures, such as grinding ore to a certain
