Production of Iron, Titanium Dioxide Modofocations and Titanium

Abstract

Conditions for the reduction of titaniummagnetite concentrates (main components are Fe 52-54 % and TiO 2 5-7 %) by natural gas for obtaining iron powder and titanium fraction were studied. Based on the theory of granulation in the drum apparatus, granules with 25 % of soda fluxing additive with optimum diameter, humidity, strength and porosity were obtained. It was found that the reduction reactions in the temperature range of 1143-1198 K are carried out if a mixture of hydrogen and carbon monoxide is added to the natural gas in amount of 15 vol %. Block-diagrams for processing titaniummagnetite concentrates for the production of iron powder α-Fe (purity 99 %), anatase and rutile modifications of titanium dioxide (99 % TiO 2 ) and titanium with a purity of 99% are presented.

Nonequilibrium Thermodynamics of Oxidative Recovery Reactions Vanadium Containing Titanomagnetite Concentrates

“…Owing to the depletion of rich magnetite ore reserves, the research has been developed on technology of titanium ore processing to produce iron, titanium, chromium and vanadium [1][2][3][4]. To determine optimal conditions of oxidation-reduction reactions, thermodynamic calculations are widely used [5][6][7][8].…”
