摘　　要：红土镍矿中含钪量为50~600 g/t,从镍钴分离富集过程中同步提取钪金属是未来非常有前景的开发利用钪资源的途径。本文首先分析了当前从红土镍矿中分离提取钪的研究现状,介绍主要提钪工艺流程,随后综述了不同浓度矿酸介质中钪的可能存在形态,以及在高酸度情况下钪的萃取机制、萃取特性和萃取条件,为红土镍矿中钪资源的充分利用提供理论指导。The content of scandium in laterite nickel ore is 50~600 g/t.The simultaneous extraction of scandium metal from the separation and enrichment process of nickel and cobalt is a very promising way to develop and utilize scandium resources in the future.In this paper,the current research status of separation and extraction of scandium from laterite nickel ore was analyzed,and the main process flow of scandium extraction was introduced.Then,the possible forms of scandium in different concentrations of mineral acid medium,as well as the extraction mechanism,extraction characteristics and extraction conditions of scandium under high acidity were reviewed,providing theoretical guidance for the full utilization of scandium resources in laterite nickel ore.
