Ores Minerals Manganese

Manganese Orean overview | ScienceDirect Topics

Major compounds of manganese, such as manganese dioxide (MnO 2) or potassium permanganate (KMnO 4), are used as depolarizers in the battery industry or as oxidation, bleaching, and disinfection agent. Most of the manganese ores (with 30–55% Mn) are mined in Ukraine, China, South Africa, Brazil, Gabun, India, and Georgia. Large amounts of manganese can be found in marine manganese nodules.

Manganese Ore Deposits

Manganese ores can be carbonates, usually rhodochrosite but sometimes kutnahorite, or various silicates and oxides, the most common being braunite, bixbyite, and hausmannite [see table of common minerals]. The carbonates carry useful isotope signals for C and O [see stable isotopes of Mn deposits]. On a purely descriptive basis, Mn ores can be,
