Sinter Quality and Process of Sintering Iron Ores – IspatGuru

Nov 21, 2014 · The surface of the iron ore core and its adhering fines are reduced to magnetite. As the temperature rises to 1100 deg C , low melting point phases such as Fe2O3.CaO, FeO.CaO and FeO.SiO2 are formed by solid-solid reactions. The phase termed SFCA (silico-ferrite of calcium and aluminum), forms at this stage.

MULTIVARIATE SIMULATION OF CHANNEL IRON ORE DEPOSITS

Jan 01, 2007 · Geostatistical conditional simulation has wide potential applications in the iron ore industry and is the favoured tool to assess variability and risk. Multivariate relationships are important in such simulation, for example between Fe and impurities such as Al2O3, SiO2 and P. Turning bands has been the main conditional simulation algorithm used in the Western Australian iron ore industry.

Iron smelting process - China piping solution supplier

Dec 31, 2020 · When smelting with self-fluxing ore, since the ore contains more CaO and it can be in good contact with acidic SiO2, CaO immediately participates in the slagging reaction at the beginning of smelting, especially when self-fluxing sintering is used. During ore smelting, CaO and SiO2 and Al2O3 formed slag early in the sintering process.

Theory and Practice of Sintering of Iron ore - IspatGuru

Based on further studies as well as initial studies, the equation which has been proposed for calculating the optimum moisture (W) as a function of the nature, composition and granulometry of the iron ore is W = 2.28 + 0.427 L + 0.810 A - 0.339S + 0.104D + 0.036 E where L is the ore weight loss during heating in grams, A is % Al2O3 in ore, S ...
