RECOVERY OF SCANDIUM AND VANADIUM VALUES FROM FEEDSTOCKS USING ULTRASOUND-ASSISTED EXTRACTION

摘要

The present disclosure broadly relates to a process for recovering scandium and/or vanadium values from various feedstocks. More specifically, but not exclusively, the present disclosure relates to a process for the selective recovery of scandium and/or vanadium values from a feedstock, the process comprising: leaching the feedstock in a sulfuric acid solution while simultaneously sonicating the sulfuric acid solution thereby producing a pregnant solution; and selectively removing scandium and vanadium compounds from the pregnant solution using a solvent extraction process.
