Flotation In Mining Iron Ore. Aug 08 2019 iron ore mining often focuses on looking for hematite deposits known as red iron ore and magnetite as they have naturally weak magnetic fields that aid in their purifiion hematite however responds better to the flotation process in iron ore beneficiation than magnetite so it is the preferred type of ore.

· Pellet Feed (<): The very fine iron ore product is obtained after the flotation process. In order to be used in the steelmaking process, it should be pelletized. At smaller percentages, it can also be blended into sinter feed and used at sintering units. The iron content of the CSN Mining pellet feed usually exceeds 66%.

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.
