Conversion of calcium sulphide to calcium carbonate during the process of recovery of elemental sulphur from gypsum waste
(Elsevier, 2014)The production of elemental sulphur and calcium carbonate (CaCO3) from gypsum waste can be achieved by thermally reducing the waste into calcium sulphide (CaS), which is then subjected to a direct aqueous carbonation step ... -
Synthesis of high-purity precipitated calcium carbonate during the process of recovery of elemental sulphur from gypsum waste
(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 ...
