2015-12-1 · Although the overall process successfully produced high-purity elemental sulphur (Nengovhela et al., 2007), the study by de Beer et al. (2014) showed that the direct carbonation of calcium sulphide (Eq.) only yielded low-purity CaCO 3 products (i.e. 86 mass% as CaCO 3).The insight gained on the solution chemistry and the characteristics of the carbonate products from
