Abstract
This invention relates to a process for beneficiating a titaniferous ore. The process comprises leaching the titaniferous ore with sulfuric acid to form a leached ore, calcining the leached ore in the presence of oxygen to form a calcined ore, and leaching the calcined ore with sulfuric acid, hydrochloric acid, and/or nitric acid to form a beneficiated ore. The leached ore is not reduced prior to or following calcination.
