WEBThe mined iron ore undergoes processing to remove impurities and improve quality. This may include crushing, grinding, magnetic separation, and/or flotation to obtain a concentrate. This is followed by sintering which means heating it to high temperatures in the presence of coke and limestone. This process produces clinker that is rich in iron. 2.
