Bulletins of Indian Industrial Research No. 15 Recovery of Titanium Oxide as a by-Product in the Manufacture of Alumina-Ferric from Bauxite

1939

The process is an adaptation of that employed in the manufacture of titanium oxide from ilmenite ; the only difference lies in the fact that while in the ilmenite process the main difficulty to be overcome is involved in the separation of the titanium oxide from iron in the process described herein the main difficulty to be overcome is the separation of titanium oxide from aluminium oxide and to [...] and it should be nod that a special feature of the process is the separation of the titanium oxide from iron--a slight trace of the latter being sufficient to tint the precipitated titanium oxide brown or yellow. [...] 1. Preparation of the mud.-Numerous samples of the mud-water that is obtained in the manufacture of alumina-ferric have been analysed and the table shows a few of the results :- Samples. [...] of titanium oxide and that the ratio of TiO2 content to Al203 content is roughly 3 to 2. It has also been found however that the meta-titanic component precipitated during hydrolysis is contaminated with aluminium hydroxide evidently due to the presence of so much alumina Moreover the pigmentive property of the titanium oxide appears to suffer if hydrolysis is conducted in the presence of an a [...] The hydrlysis is influenced by the concentration the free H2SO4 content of the soltion the temperature and duration of hydrolysis the intensity with which the solution is stirred during hydrolysis as well as by the presence of foreign sustances in the solution°.
