MS1 – First results on Sc leaching and extraction from BR

Selective leaching of Sc against iron, aluminum and titanium has been achieved from Greek bauxite residues using different  innovative technologies (leaching with mineral acid, leaching with Ionic Liquids and mechanochemical leaching with mineral acid) . Resulting leach solutions with as low as 6 mg/lt in Sc have been  utilized in the II-VI SIR process, to produce a concentrates with more than 60gr/kg Sc2O3.
