- Manganese Ore Flotation Process
The flotation of manganese ore can be used as an independent operation to produce concentrates and discard tailings; it can also be used as one of the operations in the beneficiation joint process. The flotation process is divided into positive flotation and reverse flotation. At present, industrial production mostly uses anionic collector ...

Compared to iron, the impact of manganese in sphalerite flotation is less understood. Flotation tests conducted by Greet et al. (2000) showed better recovery for sphalerite with higher manganese content. On the other hand, a study by Schouwstra et al. (2010) showed lower recovery for manganese-rich sphalerite ore. The results showed …

Flotation is a mineral separation process done in the water medium. It is based on the difference in the surface properties of the mineral and gangue. The surface of the selected mineral is made hydrophobic (water repellent) by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system and collected …

In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+, Mn 4+ must be converted into Mn 2+, therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).
