Manganese carbonate decomposes with release of carbon dioxide, i.e. calcining, at 200 °C to give MnO 1.88: MnCO 3 + 0.44 O 2 → MnO 1.8 + CO 2. This method is sometimes employed in the production of manganese dioxide, which is used in dry-cell batteries and for ferrites. [3] Manganese carbonate is widely used as an additive within plant ...
Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO 3. In its pure form (rare), it is typically a rose-red colour, [ 5 ] but it can also be shades of pink to pale brown. It streaks white, [ 6 ] and its Mohs hardness varies between 3.5 and 4.5.
Kutnohorite is a rare calcium manganese carbonate mineral with magnesium and iron that is a member of the dolomite group. It forms a series with dolomite, and with ankerite.The end member formula is CaMn 2+ (CO 3) 2, [6] but Mg 2+ and Fe 2+ commonly substitute for Mn 2+, with the manganese content varying from 38% to 84%, [2] so the formula Ca(Mn 2+,Mg,Fe 2+)(CO 3) 2 better represents the species.
Manganese has no satisfactory substitute in these applications in metallurgy. [53] Steelmaking, [74] including its ironmaking component, has accounted for most manganese demand, presently in the range of 85% to 90% of the total demand. [61] Manganese is a key component of low-cost stainless steel.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Ankerite, also known as brown spar [5]: 258 (German: braunspat) is a calcium, iron, magnesium, manganese carbonate mineral of the group of rhombohedral carbonates with the chemical formula Ca(Fe,Mg,Mn)(CO 3) 2.
Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids. These materials are white or pale pink solids.
