一、前言在钨矿选矿过程中,产出数量很大并以黄铁矿为主的多金属硫化矿,其特点是含有价元素品种多,品位低,矿相复杂。多年来,对这类矿的综合利用大都采用单一的选矿方法,其回收率较低,铜、铋、铅等为50～60%,而银则为30～40%。近年来,有人采用湿法氯化-物理选矿联合方案对这类矿进行了研究,所得到的技 I. INTRODUCTION In the process of mineral processing of tungsten ore, a large number of polymetallic sulphide ore is produced with a large amount of pyrite and is characterized by many kinds of valence elements, low grade and complex ore facies. Over the years, the comprehensive utilization of such mines mostly adopts a single beneficiation method, and the recovery rate is relatively low. Copper, bismuth and lead are 50-60%, while silver is 30-40%. In recent years, some people use wet chlorination - physical beneficiation joint program of such mines have been studied, the resulting technology
