Iron Ore Extraction

Iron ore extraction is mainly performed through open pit mining operations resulting in significant tailings generation. The iron ore production system usually involves three stages mining processing and pelletiing activities. Of these processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletiing stage.
