Abstract Scope Scandium, as the lightest rare earth element in the periodic table, has critical utilization areas such as aerospace industry, solid oxide fuel cells, electronics industry and also used in metallurgical applications. Due to the scarcity of high grade scandium deposits and high processing costs, scandium production rate is limited. It is generally produced as a co-product of primary metal processes, wastes and reprocessed tailings. Processing operations for scandium contained ores includes leaching, solution purification, ion exchange chromatography, solvent extraction, precipitation, etc. Although the previous studies were more focused on solvent extraction, ion exchange applications have also emerged as an alternative pathway. At the present time, the extraction of scandium from titanium, tungsten, uranium residues, red mud and phosphogypsum by IX have been made. The objective of this study is determining the extraction possibility of scandium from the leach solution of lateritic nickel-cobalt ore by ion exchange chromatography using various resins.
