ABSTRACT Various processes for the recovery of cerium from metallurgical, non-metallurgical and secondary sources are reviewed. Cerium is present as a major constituent of primary resources like monazite, bastnäsite, etc. Various secondary resources of cerium include phosphogypsum, red mud, blast furnace slag, NiMH batteries, FCC catalyst, glass films, CFLs, catalytic converters, etc. This review encompasses the research carried out for the extraction of cerium by pyro-hydrometallurgical methods followed by separation and purification with flowsheets. Also are enlisted in various processes like solvent extraction, ion exchange, membrane adsorption, ionic liquids, carbon-based nanomaterials, used for purification of cerium from the solution. Besides, the alternate methods to prepare cerium salts like fused salt electrolysis and metallothermic reduction are described.

从一次和二次资源中回收和再循环铈 - 批判性审查

摘要 回顾了从冶金、非冶金和二次资源中回收铈的各种工艺。铈是独居石、氟碳铈矿等初级资源的主要成分。铈的各种次级资源包括磷石膏、赤泥、高炉矿渣、镍氢电池、FCC 催化剂、玻璃膜、CFL、催化转化器等。包括为通过火法湿法冶金方法提取铈,然后使用流程图进行分离和纯化而进行的研究。还参与了各种工艺,如溶剂萃取、离子交换、膜吸附、离子液体、碳基纳米材料,用于从溶液中纯化铈。除了,
