Preparation of MANGANESE CARBONATE:
Manganese(II) carbonate is mined from its naturally occurring mineral rhodochrosite. 
The compound may be prepared in the laboratory as a palepink precipitate by adding sodium bicarbonate to a solution of manganese(II) salt saturated with carbon dioxide. 
The product obtained is monohydrate, MnCO3•H2O. 
However, if the carbon dioxide-saturated solution, together with the above monohydrate precipitate, is heated in the absence of atmosphere oxygen, the monohydrate MnCO3•H2O is converted into the anhydrous MnCO3.
