Manganese Carbonate in the Spotlight

Manganese Carbonate is a compound with the chemical formula MnCO3. Manganese Carbonate occurs naturally as the mineral rhodochrosite. Approximately 20,000 metric tonnes were produced in 2005.

Treatment of aqueous solutions of Manganese Carbonate (II) salts with alkali metal Manganese Carbonate leads to precipitation of this faintly pink solid. The Manganese Carbonate is insoluble in water but, like most carbonates, hydrolyses upon treatment with acids to give water-soluble salts.

 

Manganese Carbonate decomposes with release of carbon dioxide at 200 °C to give manganese (II) oxide:

 

MnCO3=MnO + CO2

This method is sometimes employed in the production of Manganese Carbonate dioxide for dry-cell batteries and for ferrites.

Manganese Carbonate is widely used as an additive to plant fertilizers to cure manganese deficient crops. Manganese Carbonate is used in health foods, in ceramics as a glaze colorant and flux, and in concrete stains.

Manganese Carbonate is used in medicine as a hematinic.
