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.
