Global Drivers for High Grade Concentrate | Magnetite Mines

Global Drivers for High Grade Concentrate | Magnetite MinesIron 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. The iron orebased feedstock is reduced to molten iron and slag. .
