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.
Claims8
A process for beneficiation of ilmenite ore, comprising:
- admixing ilmenite ore with an acidic solution;
- electrolytically reducing at least a portion of said ilmenite ore contained in said admixture to convert ferric iron in said ilmenite ore into ferrous iron;
- and
- dissolving a substantial portion of said ferrous iron from said ilmenite ore to produce beneficiated ilmenite ore.
