• Iron Ore Mining Techniques, Metal Extraction, Types of

  Iron ore mining is classified into two categories mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the iron oxide in a blast furnace to give iron as a result.
