Diffesale Stages In Iron Ore Process

As iron is the main component of steel it firstly needs to be made iron ore lime and coke are placed into a blast furnace and melted the resulting liquid known as molten iron is then formed as molten iron still contains around 4 – 45 impurities such as carbon which in turn make the metal brittle they need to be eradicated.
