Research Progress of Scandium Resources and Refining Technology of Scandium
Scandium resources exist extensively in China.At present,more than 800 types of scandium-contain-ing minerals have been identified.Scandium and its compounds have excellent properties,and are widely used in various modern,sophisticated scientific and technological fields of new materials,aerospace,national de-fense and military affairs.However,most of scandium is associated with minerals,which is difficult and compli-cated.The resource situation and use of scandium are summarized,the scandium-containing materials are divid-ed into three types:raw ore,industrial waste residue and industrial waste liquid,and the refining methods and examples of scandium are summarized.Based on the current status and progress of scandium extraction technolo-gy,it is proposed that the mineral processing metallurgical combined method is the main development direction for scandium extraction in the future,the hydrometallurgy process is found to effectively,improve leaching rate and reduce costs.And we further look for scandium resources and more effective refining scandium method,in scandium while recycling other high value.
