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, water-insoluble solid. Approximately 20,000 metric tonnes were produced in 2005.This would be suitable for the separation of manganese in solutions containing more magnesium than calcium impurities compared with hydroxide precipitation. In addition, manganese carbonate is a favourable form which can, after drying, be sold directly to the manganese industry or further processed for production of CMD, EM and EMD.Manganese metallurgy review.
