    Dry Iron Ore Beneficiation Iron Ore Separation ST

    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 pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.
