Calcium carbonation and the resulting precipitation of CaCO3 were concurrent with the CaS dissolution and the H2S stripping reactions. Because the production of high-purity CaCO3 could not be obtained via the direct aqueous CaS carbonation process, a two-step or indirect carbonation process route was also developed and tested.
