Abstract

To obtain titanium compounds free from iron an ore such as laminate is heated to 150-180 DEG C. with sulphuric acid of 70-90 per cent strength. The solid product is leached with a limited quantity of water in presence of a reducing agent preferably spongy iron, most of the iron sulphate being left in the solid form. The water is added little by little at a temperature not above 50 DEG C. The reduction is completed when a brown-violet coloration shows the presence of titanous salts. The solution is then treated to hydrolyze the titanium sulphate in any known way, and the first washings of the precipitated hydroxide are effected with water acidulated with sulphuric acid and containing a titanous salt so as to avoid any oxidation of ferrous salts which would injure the colour of the product. The precipitate is calcined under oxidizing conditions, for instance by blowing air through the container or through the material during calcination, or, according to the Provisional Specification, by calcining in the presence of sulphuric acid, the object being to prevent any reduction owing to organic matter that might be present. The ferrous sulphate left with the undissolved residue of the ore is recovered by solution and crystallization, and may be treated to recover the sulphuric acid. According to the Provisional Specification the solution of titanium sulphate is protected from oxidation during hydrolysis, by means of a film of oil, vaseline, or the like.
