The rutile market is segmented by type, variety, application, and geography. By type, the market is segmented into Natural Rutile and Synthetic Rutile.
A synthetic rutile with a TiO 2 content over 90 wt% and total MgO + CaO less than 1 wt% was obtained under the optimal conditions listed above. The present process can be integrated with the sulfate TiO 2 process, producing titania pigment and synthetic rutile simultaneously.
Synthetic rutile can be produced from naturally occurring ilmenite which is a complex oxide with iron. Rutile is used in the manufacture of titanium dioxidepigment. In Australia most rutile is produced from ilmenite as it naturally occurs in accessible high concentrations and in a form which allows the ready extraction of the rutile.
Synthetic rutile were manufactured by chloride reactions from the ilmenite ore, and the particle size of the synthetic rutile was 125 µm after a 30-min chloride reaction.
An improved process for the production of synthetic rutile from ore containing titanium and iron, such as ilmenite ore, by a multi-step procedure employing controlled reduction, controlled oxidation and acid leaching. More specifically, the ilmenite ore first is reduced thermally such that substantially all of the iron (III) present has been converted to iron (II) and some metallic iron.
thus, the energy requirements for producing synthetic rutile and. slag are comparable. 2.2. De ...
