Manganese carbonate MnCO3 in fine chemical industry

Manganese carbonate MnCO3, also known as the only known a bivalent manganese carbonate salt, there is no water content and a hydrate, natural water content in manganese (II) output production method is to add with co2 saturated salt solution of sodium hydroxide solution, a hydrate precipitated out under the pressurized heating, while general carbon dioxide into the solution becomes anhydride is dissolved rhodochrosite with sulfuric acid in the industry, make manganese sulfate solution, sodium carbonate solution is added to, can get MnSO4 + Na2CO3 MnCO3 + Na2SO4 anhydrous manganese carbonate crystallization is pink(trigonal system), the relative density of amorphous manganese carbonate is 3.1, while rhombohedral crystal is 3.7

Use the current domestic manganese carbonate is mostly used to produce electrolytic manganese, namely electrolytic manganese metal manganese carbonate manganese ore processing into powder, and then with sulfuric acid dissolves, electricity insert plate of cathode and anode, to produce electrolytic manganese piece a ton of electrolytic manganese piece usually need 8 tons of manganese carbonate can be used for the preparation of high purity manganese carbonate ore concentrate, is the main raw material for production of manganese sulfate electrolytic manganese metal active manganese dioxide of electrolytic manganese dioxide four manganese oxide, etc.
