Benefication of titaniferous ores

摘要

A process for beneficiation of titaniferous ores is disclosed in which a titanium and iron-containing ore, such as ilmenite is heated with potassium hydroxide, e.g. at temperatures of about 350 DEG -650 DEG C. and then treating the product with carbon monoxide and water. After cooling and washing the solid product can be separated by magnetic means into an iron-containing magnetic fraction and a titanium-containing fraction.
