Feasibility of re-processing mine tailings to obtain critical raw

Scandium is not reported to be recovered from mine tailings; it is produced mainly from primary resources and the principal source for scandium is metal imports from China (U.S. Geological Survey, 2019), from REE, and iron ore processing in Bayan Obo, China (European Commission, 2017). Hydrometallurgy processes have been suggested to recover ...
