Science Involved In Iron Mining

  • Iron Ore Mining Techniques Metal Extraction

    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 since iron ores consists of the element iron combined with other elements, mostly oxygen. Haematite and magnetite are the most commonly found iron ore minerals.

    The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage. The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water.
