    Charging. After the ground ores have been processed in forms of sinter and pellets (see article iron ore mining and dressing), they are stored in bunkers in the iron works and mixed with lump ore as required.Before this mixture is then fed to the blast furnace together with coke as fuel, additives are added (also called fluxes).These mixture is referred to as charge.

    The iron ore sintering process is the main source of SO 2 emissions in the iron and steel industry. In our previous research, we proposed a novel technology for reducing SO 2 emissions in the flue gas in the iron ore sintering process by adding urea at a given distance from the sintering grate bar. In this paper, a pilot-scale experiment was carried out in a commercial sintering plant.
