Manganese plays a crucial role in different steelmaking processes, including excess sulfur and oxygen removal (Zhang and Cheng 2007).In addition, manganese is an essential alloying element in ferromanganese steels, low-cost stainless steels, and aluminum alloys (Kim et al. 2016).Besides, manganese is a crucial constituent of some electrical devices.

Because the density of manganese oxide ore such as pyrolusite, pyrolusite, and brown manganese ore is about 4g/m³, which is significantly different from the density of silicate gangue, most of them can use gravity separation. Manganese carbonate ore mostly adopts the combined process of dense medium and strong magnetic separation.
