What is manganese carbonate?
Manganese carbonate with the chemical formula MnCO3 is an inorganic and water-insoluble compound. Manganese carbonate crystals are light pink and almost white when it is precipitated. The global production of this compound is estimated about 34000 metric tons in 2018. The mineral MnCO3 is rhodochrosite, which, along with pyrolusite, is one of the main sources of manganese. This material, with 114.95g/mol molecular weight, is slightly soluble in water.
Manganese carbonate production method
MnCO3 has a density of 3.12 grams per cubic centimeter and decomposes during heating and produces manganese monoxide and manganese dioxide. This reaction can take place in rotary kilns or multiple hearth furnaces. When the temperature reaches 320 degrees Celsius, the manganese monoxide is produced with the chemical formula MnO and brown color, which is soluble in sulfuric acid. As the temperature rises to 800 degrees Celsius, manganese dioxide is produced with the chemical formula MnO2, which is insoluble in water and sulfuric acid and is black. Both of these materials are used as pigments. Also, the high-grade manganese dioxide obtained from this method can be used to produce pure and high-quality potassium permanganate.
High-grade, pure, silica-free MnCO3 is used to produce manganese ferrite magnets. Manganese ferrite is produced by combining manganese carbonate and iron oxide. Manganese ferrite nanoparticles have an important application in the production of electronic equipment.
Uses and applications of MnCO3
- Production of some drugs
- Production of various manganese compounds such as manganese phosphate, manganese chloride and pure manganese dioxide
- Used in welding wire production plants
- Chemical industry
- Used in agriculture as a long-term supplier of manganese
- Used in zinc and copper ingots plants as lead anode protectors in electrolysis cells
- Nickel electroplating as a stabilizer
- Manganese ferrite production
- Ferromanganese Production
How to produce manganese Carbonate
Manganese carbonate is produced by the reaction of alkaline carbonates such as sodium carbonate (Na2CO3) and sodium hydrogen carbonate (NaHCO3) with manganese sulfate. During this reaction, MnCO3 is precipitated, and soluble sodium sulfate is produced as a by-product.
MnSO4 + Na2SO4 → MnCO3 + Na2SO4
This chemical precipitates are separated after filtration. The filtered cake is milled, after drying in a rotary dryer, and packaged and ready for sale. Sodium sulfate filtrate will also turn into heptahydrate crystals after condensing and will be ready for packaging.
