摘　　要：钪作为一种稀土金属,在许多行业得到了广泛的应用。从含钪废弃物中回收钪,不仅可以解决废弃物污染环境的问题,还可以缓解我国钪供应量严重不足的现状。本文综述了从各种含钪废弃物(赤泥、钛白废酸、钨渣、粉煤灰)中回收钪的研究进展,并对我国钪回收工艺技术的发展进行展望,指出钪回收工业将向高效化、低成本化和绿色化的方向发展。As a rare earth metal,scandium has been widely used in many industries.Recycling scandium from scandium-containing wastes can not only solve the problem of environmental pollution by waste,but also alleviate the serious shortage of scandium supply in China.In this paper,the research progress of scandium recovery from various scandium-containing wastes(red mud,titanium dioxide waste acid,tungsten slag,fly ash)is reviewed,and the development of scandium recovery technology in China is prospected.It is pointed out that high efficiency,low cost and environmental protection are the development direction of the scandium recovery industry.
