摘　　要：随着航空航天和新能源汽车等众多新兴行业的快速发展,对钪的需求量也逐渐增加,导致目前所生产的钪越来越不能满足需求,赤泥的高储量及其相对较高的钪含量,使其有望成为未来钪的直接来源。评述了从赤泥中回收钪的工艺方法,重点列举与分析了采用湿法冶金工艺及火法-湿法冶金联合工艺粗提钪的具体方法及主要优缺点。最后指出降低酸耗、水耗,最大限度提高钪的回收率,并实现赤泥中有用组分的综合回收利用是未来研究的发展方向。With the rapid development of many emerging industries,such as aerospace and new energy vehicles,the demand for scandium is also increasing.As a result,the scandium currently produced could not satisfy its requirement increasingly.High reserves of red mud and its relatively high scandium content made it possible to be a direct source of scandium in the future.The processes for recovering scandium from red mud were reviewed,and the specific methods and the main advantages as well as disadvantages of the two rough processing technologies including hydrometallurgy process and pyro-hydrometallurgical combined process were listed and analyzed.Finally,the development direction of future research was to reduce acid and water consumption,maximizes the recovery of scandium,and makes the comprehensive recovery and utilization of useful components in red mud.
