Synthesis of high-purity precipitated calcium carbonate during the process of recovery of elemental sulphur from gypsum waste

De Beer, M.; Liebenberg, L.; Doucet, F.J.; Maree, J.P. (Elsevier, 2015)

We recently showed that the production of elemental sulphur and calcium carbonate (CaCO3) from gypsum waste by thermally reducing the waste into calcium sulphide (CaS) followed by its direct aqueous carbonation yielded ...
