Despite the rich reserves of ferromanganese ore, it can only be discarded as waste rock due to the difficulty of its development and the unavailability of conventional methods. In this study, suspension magnetization roasting (SMR) and low-intensity magnetic separation (LIMS) were used to process ferromanganese ore.
The development of even more powerful magnet materials led to the implementation of permanent magnets to create the magnetic field. LIMS typically relies on strontium ferrite magnets while MIMS (Medium Intensity Magnetic Separators) commonly use an alloy of neodymium, iron, and boron (NdFeB).
