Cobalt(II) carbonate (CoCO₃) is a reddish paramagnetic solid that functions as an intermediate in the hydrometallurgical extraction of cobalt from ores. This compound serves both as an inorganic pigment and a precursor for catalyst synthesis. Naturally occurring as the rare mineral spherocobaltite, which exhibits red to pink coloration, it is commonly produced industrially by precipitation from cobalt sulfate solutions using sodium bicarbonate.
