稀土固体废物的成因、成分分析及综合利用

Formation Cause,Composition Analysis and Comprehensive Utilization of Rare Earth Solid Wastes

根据稀土工业产业链实际情况,就产生批量固体废弃物的工艺过程及稀土材料进行了讨论,对稀土湿法冶金渣、电解渣、铁基稀土永磁材料、钴基稀土永磁材料、稀土贮氢材料、稀土抛光粉、稀土催化剂等固体废物的成因、生成量、成分分析及综合利用进行了综述,并对稀土固体废物的处理及管理提出了建议。

Based on practical situation of rare earth industrial chain,production process and rare earth materials that could produce solid wastes on batch are discussed in this paper.Formation cause,formation volume,composition analysis and comprehensive utilization of the solid wastes of rare earth hydrometallurgy slag,electrolysis slag,Fe-based rare earth permanent magnetic materials,Co-based rare earth permanent magnetic materials,rare earth hydrogen storage materials,rare earth polishing powders and rare earth catalysts are comprehensively introduced.Besides,some suggestions on treatment and administration on rare earth solid wastes are put forward.
