Iron ore beneficiation encompasses a wide range of process steps. Crushing, screening and grinding are physical processes used to liberate small particles of differing composition, and are often used together in multiple stages [4], [5]. Thermal breaking has also been suggested as a pre-treatment to reduce grinding costs [6].
