Manganese(II) carbonate 99.9+ trace metals 598-62-9

Manganese (II) carbonate is a chemical compound that has a structure similar to calcite, with octahedral co-ordination symmetry. It is a carbonate that is insoluble in water and on treatment with acid it gives water soluble salts. It is a widely used material in plant fertilization as an additive that cures the magnesium deficiency in crops.

Anoxic photogeochemical oxidation of manganese …

It is generally assumed that the oxidation of manganese minerals requires biological catalysis or molecular oxygen and therefore is often used as a proxy for the presence of oxygenic photosynthetic organisms. We show that anoxic, abiotic oxidation of the mineral rhodochrosite (MnCO 3) by UV light forms H 2 and manganite (γ-MnOOH).
