PURIFICATION OF ILMENITE ORE BY OXIDIZING ROASTING WITH PRE- AND POST-MAGNETIC SEPARATION

摘要

ABSTRACT OF THE DISCLOSUREPurification of ilmenite from chromite impurities bya two step magnetic separation wherein magnetically susceptiblechromite is magnetically removed, followed by an oxidizingroasting of the ilmenite and a subsequent magnetic separationof ilmenite from the remaining chromite impurities to obtainan ilmenite with 1% or less chromite.
