Cobalt(II) carbonate (CoCO3) is a reddish, paramagnetic solid and serves as an intermediate in the hydrometallurgical process of extracting cobalt from its ores. It is used as an inorganic pigment and as a precursor to catalysts. Cobalt(II) carbonate is also found in nature as the rare red/pink mineral spherocobaltite. It is typically synthesized by reacting cobaltous sulfate with sodium bicarbonate solutions.
