Abstract: 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.
