Abstract
A process for beneficiating ilmenite ore using electrolytic reduction. The ilmenite ore is admixed with an acidic solution to form a mixture. The mixture is electrolytically reduced to convert at least a portion of any ferric iron that is present to ferrous iron. The acidic solution dissolves the ferrous iron in the ilmenite ore and yields beneficiated ilmenite having a relatively high titanium dioxide content.
