This paper examines the effectiveness of the method for producing synthetic rutile from ilmenite through pre-oxidation and reductive leaching of pre-oxidized ilmenite in hydrochloric acid. Thermodynamic simulation of the pre-oxidation of ilmenite concentrate was performed to evaluate the phases formed during the process as a function of temperature. The pre …

The major sources of TiO 2 are natural rutile, synthetic rutile, and high titanium slag [3]. Production of synthetic rutile includes the processes to remove iron from ilmenite giving a concentrate ...

The traditional methods for producing synthetic rutile from ilmenite consist of the smelting, Becher, hydrochloric acid leaching and sulfuric acid leaching processes [3]. In the smelting process [4], the iron in ilmenite is reduced to metallic iron over 1600 ° C and the melted iron is then separated from the titanium-containing slag phase to ...

The synthetic rutile can be obtained by selective thermal decomposition of the sulfated ilmenite, followed by targeted leaching for removal of various impurities.

Other sources of raw material for the production of titanium dioxide are slag produced during iron smelting and synthetic rutile produced from ilmenite.
