beneficiation of titaniferous magnetite

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 350-650 C and then the product is treated 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 ...
