摘　　要：钨渣中不仅含有W、Sn、Ta、Nb等有价元素,还含有As、Pb等有毒元素,随意堆放或者填埋,不仅对环境造成污染,还会浪费其作为二次资源的价值。本文综述了湿法冶金、选-冶联合、火法-湿法联合、火法冶金等碱煮钨渣综合回收利用技术的研究进展,分析了各自存在的技术优势和问题,并指出火法冶金具有工艺流程短的特点,将成为碱煮钨渣综合利用技术的发展方向。Tungsten slag contains not only valuable elements such as W,Sn,Ta and Nb,but also toxic elements such as As and Pb.If tungsten slag is randomly stacked or buried,not only the environment will be polluted,but also its value as secondary resources will be wasted.This paper reviews the research progress of comprehensive recovery and utilization technologies of alkali-boiled tungsten slag,such as hydrometallurgy,beneficiation-metallurgy combination,pyro-hydrometallurgy combination and pyrometallurgy.Their technical advantages and disadvantages are analyzed.It is pointed out that pyrometallurgy has the characteristics of short process flow and will become the development direction of comprehensive utilization technology of alkali-boiled tungsten slag.
