Iron - Wikipedia

  

2019-10-7  Nowadays, the industrial production of iron or steel consists of two main stages. In the first stage, iron ore is reduced with coke in a blast furnace, and the molten metal is separated from gross impurities such as silicate minerals. This stage yields an alloy -- pig iron—that contains relatively large amounts of carbon.
