The Sintering Process of Iron Ore Fines – IspatGuru

The sintering process is used to agglomerate a mix of iron ores (blend), return fines, fluxes and coke, with a particle size of less than 10 mm, so that the resulting sinter, with a screened size of 10 mm to 30 mm, can withstand pressure and temperature conditions in the blast furnace. Principle of sintering. Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a ...

Mining of Iron Ores – IspatGuru

Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). The process ...
