Iron ores come in come in many shapes and sizes (and mineralogies), so there is no one size fits all approach to beneficiation. For magnetite ores, it is typically necessary to liberate the individual magnetite grains from the host rocks, after which beneficiation is relatively straightforward due to the magnetic properties of magnetite.
