The content of scandium in laterite nickel ore is 50~600g/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.
