摘要:

钨矿的冶炼势必伴随产生大量钨冶炼渣,作为危险固废的冶炼渣含有丰富的有价金属,直接堆积于尾矿库不仅会污染环境、占用土地,还会造成金属资源的浪费。因此,很有必要采用合适的选别工艺技术处理回收钨冶炼渣中Sn、W、Sc、Fe、Mn、Ta和Nb等有价金属,一方面能从源头减少钨冶炼渣排放量,另一方面增加有价金属循环利用率。文章详细阐述钨冶炼渣中不同有价金属选别回收的工艺方法,并对比了不同方法各自存在的优势和弊端,同时也指出了钨冶炼渣被用于生产不同特殊材料的现状。在此基础上,展望了未来钨冶炼渣处理技术的发展方向,为更好综合利用钨冶炼渣提供借鉴。

Abstract:

The smelting of tungsten ore is bound to produce a large amount of tungsten residue. As a dangerous solid waste, the residue is rich in valuable metals. Direct accumulation in the tailings pond will not only pollute the environment and occupy land, but also cause waste of metal resources. Therefore, it is necessary to use suitable sorting technology to treat and recover valuable metals such as Sn, W, Sc, Fe, Mn, Ta and Nb in tungsten residue. On the one hand, it can reduce the discharge of tungsten residue from the source, and on the other hand, it can increase the recycling rate of valuable metals. The article elaborated on the separation and recovery of different valuable metals in tungsten residue, and compared the advantages and disadvantages of different methods. At the same time, it also pointed out the current situation that tungsten residue is used to produce different special materials. On this basis, the future development direction of tungsten residue treatment technology is prospected, which provide reference for better comprehensive utilization of tungsten residue.

Key words: tungsten residue, valuable metal, leaching, roasting, recovery
