RECOVERY OF SCANDIUM FROM TITANIUM TAILINGS

RECOVERY OF SCANDIUM FROM TITANIUM TAILINGS SOLUTION USING II-VI SIR TECHNOLOGY Gomer ABRENICA1 plant was built. The acid waste solution was treated to remove Ti. The solution from the Ti Removal step contained low concentration of Ti, Th, Nb and Zr. During the pilot plant operation, 95% recovery of Sc through SIR IX was achieved. The crude Sc
