Molten salt electrolytic beneficiation of iron oxide-containing titaniferous ores to produce iron and high-grade TiO.sub.2

摘要

Disclosed is a process for beneficiating titaniferous material which contains iron oxide. The titaniferous material is mixed with a molten salt or mixture or molten salts in which iron oxide dissolves to produce iron ions and oxyanions. The iron ions are electrolytically reduced to iron at the cathode and deposited as high purity iron on the cathode. The oxyanions react with a carbonaceous anode to generate CO and/or CO.sub.2. A beneficiated TiO.sub.2 product is recovered from the molten salt or mixture of molten salts.
