Importantly, magnetite is suitable for processing into iron ore pellets for use in modern steel production and currently accounts for approximately 50% of global iron ore production. The magnetic properties of magnetite enable it to be readily refined into an iron ore concentrate used as high-quality feedstock for the production of premium quality,
Rinse Water System: Centrifugal concentrators often have a system for introducing water, which helps to create a fluidized bed and assists in the separation process. Rotation Mechanism: The bowl is rotated at high speeds by a motor. This rapid rotation generates a powerful centrifugal force, which drives the separation process.
Demand for iron ore worldwide has been steadily increasing which leads to the extraction of iron ore deposits with more complex mineralogies and higher levels of silicon and phosphorus impurities.
