Understanding Magnetite Ore Beneficiation: Magnetite ore beneficiation is a process of extracting valuable minerals from raw ore through various techniques to enhance its quality and purity.
The aim of this project was to investigate ferrosilicon replacement through the use of spherical magnetite in water in a wet heavy medium. By replacing this ferrosilicon with a waste product from titanium sand processing (spherical magnetite), it was hoped that higher density media would be achieved in a fluidized bed without reaching a viscous limit.
