Generally, the surface dissolution pretreatment by oxalic acid can easily and effectively improve the selective flotation of ilmenite from iron containing gangue minerals. This organic reagent also assists to this improvement by depressing the gangue minerals when it is used as a pH adjuster agent.

Ilmenite

ilmenite displays poor flotation under conventional flotation conditions in comparison 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.

PowerPoint Presentation

SYB2# (a category of hydroxamic acid) was employed as the collector of ilmenite flotation. Sodium carboxymethyl cellulose was employed as the depressor of gangue, and sulphuric acid as the pH adjustor of flotation. The effect of pH values on the recovery of ilmenite and gangue was investigated on the condition with (or without) depression respectively.
