CONCRETE MATERIALS AND TESTING

In the blast furnace, magnetic iron ore (Fe3O4) and haematic iron ore (Fe2O3) are fed along with limestone into a high temperature chamber containing coke. Coke is partially oxidized to carbon monoxide, which reduces the ores to iron. The other product that floats over the molten iron due to its relative lightness is called slag.
