  • Dry Benefication Of Low-Grade Iron Ore Fines Using a Tribo
    Dry Benefication Of Low-Grade Iron Ore Fines Using a Tribo

    Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation [2]. 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

    Upgrading Low-Grade Iron Ore through Gangue Removal

    In this study, a combination of alkali roasting and hydrothermal treatment is used as a method of gangue (Si, Al, and P) removal from iron ores as a means to upgrade low-grade iron ore (limonite) into a high-grade iron ore with low gangue content, low porosity, and high Fe and Fe 2 O 3 content to enhance the sustainable development of iron and steel industries
