Theory and Practice of Sintering of Iron ore. Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix raw mix or green mix of iron ore fines, fluxes, fuel coke breeze and plant return fines e.g. mill scale, blast furnace dust, and returned sinter fines etc.
Iron Ore Iron ores are rocks and minerals from which metallic iron can be economically extracted. Iron ores that carry a high quantity of hermatite or magnetite can be fed directly into blast furnaces in the iron production industry.
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.
Iron Ore Pellets Iron ore pellets are spheres of typically 616 mm 0.240.63 in to be used as raw material for blast furnaces. They typically contain 67-72 Fe and various added material adjusting the chemical composition and the metallurgic properties of the pellets.
