摘要： A method of separating scandium from a feedstock wherein a scandium enriched solution is produced from the feedstock and the scandium enriched solution is extracted to produce an organic phase of the scandium enriched solution. The organic phase of the scandium enriched solution is re-extracted to produce an aqueous phase including scandium chloride. The aqueous phase is precipitated and calcinated to produce scandium oxide powder.
