Magnetite ore is a ferromagnetic material, with the chemical formula Fe3O4, and is one of several types of iron oxide.It is a ubiquitous mineral in many parts of the world, including Australia, the USA, Canada, South Africa, Mozambique and many other countries across most of the world's continents.
problem in iron ore smelting process. However, the magnetic separation of pyrrhotite from magnetite is problematic, due to their similar magnetic property and magnetic flocculation between pyrrhotite and magnetite [3]. Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores [4].
