Manganese carbonate is an inorganic compound of the chemical formula MnCO3, which is found in the nature in the form of a diamond manganese ore. Global output in 2005 was about 20,000 tons.
1. dissolving manganese metal in nitric acid for reaction by a metal manganese method, purifying the generated manganese nitrate solution with hydrogen sulfide to remove heavy metals, filtering, carrying out metathesis reaction on the manganese nitrate purification solution and ammonium bicarbonate to generate manganese carbonate, and washing, filtering, dehydrating and drying the precipitate to obtain a high-purity manganese carbonate finished product. The reaction equation is as follows: 2. dissolving manganese sulfate with water or steam in a reactor by a metathesis method, filtering to remove insoluble substances, purifying with hydrogen sulfide to remove impurities such as heavy metals, heating, boiling, and filtering while hot to obtain a pure manganese sulfate solution. Then carrying out metathesis reaction with ammonium bicarbonate solution in a reactor at 25 – 30 deg c to generate manganese carbonate, filtering, washing and dehydrating the precipitate, and carrying out hot air drying at 80 – 90 deg c to obtain the manganese carbonate finished product. The reaction formula is as follows:
3. mix pyrolusite powder with coal pow by pyrolusite method, reducing roasting, leaching with sulfuric acid to obtain manganese sulfate solution, filter, neutralizing with ammonium bicarbonate, vacuum filtering, dehydrating, and drying to obtain manganese carbonate. The reaction formula is as follows
4. mix sulfuric acid solution and rhodochrosite powder accord to a certain proportion for reaction by a rhodochrosite method, purifying and separating that generated manganese sulfate solution, adde ammonium bicarbonate for neutralization, washing, dehydrating and drying to obtain the manganese carbonate product. The reaction formula is as follows: …
