Magnetite ore beneficiation is practiced to generate an iron based mineral concentrate containing much of the vanadium with low silica levels of 2%. Typical processing problems encountered are fine liberation size, over grinding of the magnetite and variable response to magnetic separation resulting from the ore weathering profile. Beneficiation options are restricted, and generally focused on producing a combined iron and titanium rich concentrate containing vanadium due to the fact that ilmenite and magnetite and their products of weathering are magnetic and have similar specific gravities making their separation difficult. The ilmenite usually contains low levels of vanadium making its separation highly desirable from the iron mineralisation containing higher levels of vanadium. Silica and alumina are specific contaminants that must be at low levels in the concentrate.
