摘　　要：我国是钨产业大国,却缺少有效的钨渣工业化处理方式。随着钨矿的大肆开采,传统的填埋方式已不适用于处理现有钨渣,导致钨渣不断堆积。同时,钨渣中的重金属等成分对环境有严重污染。对此,许多学者致力于解决钨渣堆积的问题,开展了大量的研究,拟对钨渣中有价金属进行综合回收与利用。本文概述了近年来国内外回收与利用钨渣技术的研究进展,主要分为回收钨渣中有价金属和利用钨渣制作特殊材料。最后,对钨渣回收利用的发展趋势进行了展望。China is a large country of tungsten industry, but there is a lack of effective industrialized treatment methods for tungsten slag.With the extensive exploitation of tungsten ore, the traditional landfill method is no longer suitable for the treatment of existing tungsten slag, resulting in the continuous accumulation of tungsten slag.At the same time, heavy metals in tungsten slag have caused serious environmental pollution.In view of these problems, many scholars are committed to solving the problem of tungsten slag accumulation and have carried out a lot of research to comprehensively recover and utilize the va-luable metals in tungsten slag.This paper summarizes the research progress on the recovery and utilization technology of tungsten slag at home and abroad in recent years, which is mainly divided into the recovery of valuable metals in tungsten slag and the use of tungsten slag to make special materials.Finally, the deve-lopment trend of tungsten slag recycling is prospected.
