【摘要】：Red mud is a slimy caustic residue generated from alumina production. Taking into account the relatively considerable content and availability of scandium,red mud can be viewed as an important and promising scandium resource rather than a solid waste. This paper is primarily to review the investigations of scandium recovery from red mud based on the most widely used hydrometallurgical processes including acid leaching, solvent extraction and ion exchange adsorption. It is thought that recovery of scandium from red mud should be considered as a direct objective rather than a by-product in the development of overall flowsheet. In order to achieve environmentally-friendly processes with high scandium recovery and low cost, more attention is required to be paid to optimizing the selective leaching of scandium to decrease mineral acid consumption and alleviate pollution,and developing new solvent extraction systems and novel ion exchange adsorption materials with high selectivity and recognition for scandium.
