钨渣综合利用研究现状

随着钨矿资源的大量开发和利用造成钨渣的露天堆存，这不仅会造成有价金属资源的浪费，而且堆存占用大量土地，导致土壤和地下水系严重的污染。阐述了钨渣浸出毒性与特征污染物，分析钨渣资源化存在的问题，对现有钨渣回收钨、钽、铌、铁、锰、钪、锡和铀工艺与钨渣减量化处理研究现状进行了综述，并对未来钨渣资源化与减量化研究方向提出了建议。 

Research Status of Comprehensive Utilization of Tungsten Slag

The extensive development and utilization of tungsten resources have caused the open storage of tungsten slag. It will not only cause the waste of valuable metal resources, but also cause serious pollution of soil and groundwater due to the large amount of land occupied by the stockpiles. This paper described the leaching toxicity and characteristic pollutants of tungsten slag. The problem of the resource of tungsten slag was analyzed. The current research status of the process of recovering tungsten, strontium, barium, iron, manganese, antimony, tin and uranium from tungsten slag and tungsten slag reduction treatment was reviewed, and the future research directions of tungsten slag reclamation and reduction were put forward.
