Iron Ore Sinter Magnetism

Import of iron ores into China is signicant and rising. Domestic ores for sintering in China are primarily mag-netite concentrates. Many Chinese sinter plants use import-ed ores and domestic magnetite concentrates in their blends, and the level of imported ores varies signicantly from mill to mill.

    Vanadiumtitanium Magnetite Ore Blend Optimization For

    Sep 10, 2015 Due to the fact that the iron ore sintering is a non-uniform process, in order to avoid the decrease of the nuclei ores in the consolidation framework and the deterioration of the permeability of the sintering bed, the assimilation ability of iron ores is not desired to be too high, which may cause over-melting and has a negative effect on the yield and quality of the sinter Wu et al., 2010 . Therefore,

    Reduction Of Iron Ore Pellets Sinter And Lump Ore Under

    Mar 23, 2020 The reasons behind this reduction behavior are the following 1 the lump ore is slowest to reduce in all temperatures because it has the smallest reaction surface area, and the structure is not porous and 2 compared with iron ore pellets and lump ore, sinter has the highest proportion of magnetite, which does not easily reduce as hematite at low temperatures.

    Compared with the sintering of ordinary iron ore, vanadium-titanium magnetite has lower iron, FeO, and SiO 2 contents but higher TiO 2, MgO, and Al 2 O 3 contents. These characteristics are not favorable for sintering, resulting in low production, low grade, poor strength, low yield, and high solid energy consumption of the sintered ore 1 , 2 .
