    The upper tailings usually contain pyrrhotite pyrite ± chalcopyrite calcite quartz andradite and diopside. The lower tailings mainly contain goethite quartz chlorite muscovite calcite and hematite ± pyrrhotite. These assemblages clearly relate to the original types of gold deposit prior to mining and mineral processing.

    Typically hematite is mined by open pit mining. Overburden is removed then the ore is mined from an ever-deepening hole. The mineral and rock is first stripped by blasting the rock with explosives and removing it with enormous truckswith capacities over 150 tons. The ratio of mineral to rock can be quite largeup to 1.5 to 1 for hematite.
