Promoting assimilation of magnetite fine ore for CO2

Fe content in hematite ore is gradually decreasing. The usage low Fe ore in sintering process increase the volume of a bonding agent as fuel in order to maintain the yield and the strength of sinter ores. However the usage of a bonding agent cause more CO2 emissions. Therefore, a magnetite ore has been focused because it can perform magnetic separation and can produce a large amount of .
