Zinc carbonate is the inorganic zinc salt of carbonic acid (CAS 3486-35-9; ZnCO3, MW 125.39), occurring naturally as the mineral smithsonite. At about 52% elemental zinc it carries a high elemental load, above the organic-acid salts and chelates though below the oxide and sulfate, and like the oxide it is only sparingly soluble in water. Commercial dietary grades are frequently supplied as basic zinc carbonate (zinc carbonate hydroxide, CAS 5263-02-5), which differs slightly in composition and zinc assay. It is a white powder manufactured into tablets, capsules and powder blends.
