EFFECT OF OXIDATION ROASTING ON ILMENITE FLOTATION

with other oxide minerals such as magnetite and rutile. The poor flotation of ilmenite requires a large dosage of flotation reagents to promote ilmenite surface hydrophobicity and attachment to air bubbles. Even a large dosage of collectors gave flotation recovery of less than 80% for ilmenite (Zhong and Cui 1987; Pownceby et al.
