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 ...

Ilmenite Concentrate Properties and Processing Methods
Metallurgist, 2013Physicochemical and production properties of ilmenite concentrates are studied in order to determine the possibility of preparing from them the required titanium-containing industrial materials. Data are provided for ilmenite concentrate fraction, mineralogical, and thermographic analyses.

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 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.

Reducing roasting of the ilmenite concentrates of deposit Tsentral’noe
Russian Metallurgy (Metally), 2011The reducing roasting of the titanium-containing concentrates of deposit Tsentral’noe is studied over a wide range of operating conditions to develop a new technology of processing to exclude melting in an electric furnace. The roasting products are investigated by scanning electron microscopy and electron-probe microanalysis.

Chlorination of reduced ilmenite concentrates and synthetic rutile
International Journal of Mineral Processing, 2011Chlorination of reduced ilmenites of different grades (primary, secondary and HYTI 70) and synthetic rutile was investigated at 235 °C. The main phases of primary and secondary ilmenites were FeTi O and FeTiO; HYTI 70 contained TiO ; synthetic rutile consisted of titania with titanium suboxides and trace amount of iron.

Becher Method Application for Ilmenite Concentrates of Vietnam
2020Several methods used to extract iron from ilmenite concentrate to increase TiO2 content of ilmenite concentrates such as Benelite, Ishihara, Murso, Austpac, and Becher methods. Benelite method uses HCl for leaching of reduced iron from ilmenite. Auspac method uses hot HCl while Ishihara uses hot acid H2SO4 in the leaching stage.

Preparation of nanosized synthetic rutile from ilmenite concentrate
Minerals Engineering, 2010Abstract In this paper, the preparation of nanosized synthetic rutile by reductive hydrochloric acid leaching of mechanically activated ilmenite concentrate (FeTiO 3 ) is discussed. X-ray fluorescence analysis of the nanosized rutile which forms by rapid hydrolysis of dissolved titanium indicates that the powder contains 91.1% TiO 2 , 1.3% Fe 2 O 3 ,

Izvestiya. Ferrous Metallurgy
Russia has an impressive titanium mineral resource while the contribution into the global production of titanium concentrates is quite insignificant. The current annual demand of Russian enterprises for titanium raw materials is 40 times higher than its production. To improve and launch the processing of domestic titanium raw materials characterized by

Review of processing conditions for Murray Basin ilmenite concentrates
Mineral Processing and Extractive Metallurgy, 2014Australia is a major world producer of heavy minerals from mineral sand deposits, but to maintain its premier position in the world market place, the development of large resources such as in the Murray Basin will be necessary. There are two types of deposits in the Murray Basin, the fine-grained (20–80 μm) WIM-type deposits and those with coarser ...
