Global Drivers for High Grade Concentrate - Magnetite
Iron is extracted from iron ore in a blast furnace by a process known as reduction. The raw materials – iron ore, coke and fluxes – are fed into the top of the furnace. Air, which is heated to about 1200°C, is blown into the furnace through nozzles. The air causes the coke to burn which creates the chemical reaction.
