Thermochemical transformations of ilmenite – leucoxene concentrate
Glass and Ceramics, 2010Porous silicate-ferropseudobrookite composite material manifesting the properties of a ceramic n-type semiconductor has been synthesized by vacuum-heat treatment of ilmenite – leucoxene concentrate modified by additions of magnesium oxide. The microstructure and the chemical and phase compositions are described, and the mechanical and electrophysical ...

Effect of wet grinding on carbothermic reduction of ilmenite concentrate
International Journal of Mineral Processing, 2015Abstract High titania slag has become a good raw material in the development of titanium. Ilmenite is reduced first and then smelted in an electric arc furnace to separate iron from the high titania slag. Therefore, enhanced reduction of ilmenite concentrate can reduce smelting time and energy consumption.

Microwave reduction of oxidised ilmenite concentrates
Minerals Engineering, 1995Abstract This paper covers preliminary investigations into the novel use of microwave energy as a heat source for the partial reduction of oxidised ilmenite (FeTiO3) concentrates. Microwave energy has potential for the speedy and efficient heating of minerals and in a commerical context may provide savings in both time and energy.

Effect of preoxidation on the reduction of ilmenite concentrate powder by hydrogen
International Journal of Hydrogen Energy, 2019Abstract In this study, hydrogen reduction of raw and preoxidized ilmenite concentrates powder, with particle size less than 74 μm, is investigated using a thermal analyzer at 1123, 1173, and 1223 K in a 30% H2 + 70% Ar atmosphere. The reduction rate by hydrogen was found to be accelerated due to preoxidation treatment of the raw ilmenite concentrate.

Effect of preoxidation and sintering on properties of ilmenite concentrates
International Journal of Mineral Processing, 2002Abstract The paper examines the effects of preoxidation and sintering on the phase composition, specific surface area, morphology and reducibility of ilmenite concentrates. Samples were preoxidised in air or sintered in argon by temperature-programmed heating to temperatures of 600–1400°C at a ramping rate of 300°C/h.
