  • Titaniferous ore beneficiation
    Patent number: 7494631
    Abstract: This invention relates to a process for beneficiating a titaniferous ore. The process comprises calcining the titaniferous ore, at least one alkali or alkaline earth metal salt, and at least one alumina-containing material in the presence of oxygen to form a calcined ore mixture, then leaching the calcined ore mixture with a solution comprising ammonium, sodium or magnesium chloride in the presence of oxygen to form a leached ore mixture, and contacting the leached ore with an acid to form a beneficiated ore.
