Two Minerals That Were Blasted During Early Process Of Iron Ore Extraction

Projects List

  • Iron Ore Mining  Techniques  Metal Extraction

    Iron Ore Mining Techniques Metal Extraction

    Haematite and magnetite are the most commonly found iron ore minerals the smelting process allows the iron ore to be heated with carbon the carbon combines with the oxygen and carries it away leaving behind iron blast furnaces are so hot which is why they melt the iron and drain it off to be poured into moulds to form bars called ingots
