Manganese carbonate is a compound with the chemical formula Mn CO 3.Manganese carbonate occurs naturally as the mineral rhodochrosite but it is typically produced industrially. It is a pale pink, waterinsoluble solid. Approximately 20,000 metric tonnes were produced in 2005.
Magnetic Properties of Low Grade Manganese Carbonate Ore
Rapid reduction roasting of low grade manganese carbonate ore by coal and biomass fuels from Hunan, China was investigated. Magnetic separation behaviors and magnetic properties of raw manganese ore and roasted manganese ores were analyzed. After reduction by coal and biomass fuels, the manganese ores demonstrate a new MnFe oxide phase, showing obvious mixed magnetic
Manganese Carbonate is a water insoluble Manganese source that can easily be converted to other Manganese compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Manganese Carbonate is generally immediately available in most volumes.
