Conversion of calcium sulphide to calcium carbonate during the process of recovery of elemental sulphur from gypsum waste

Author: De Beer, Morris ; Maree, JP ; Liebenberg, L ; Doucet, FJ Date: Nov 2014 The production of elemental sulphur and calcium carbonate (CaCO(sub3)) 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 for the generation ...

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

Author: De Beer, Morris ; Doucet, FJ ; Maree, JP ; Liebenberg, L Date: Aug 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 low-grade carbonate ...

Valorisation of chicken feathers: Characterisation of thermal, mechanical and electrical properties

Author: Tesfaye, T ; Sithole, Bishop B ; Ramjugernath, D ; Mokhothu, Thabang H Date: May 2018 Increasing consumption of chicken results in generation of large amounts of wastes that need to be disposed of properly. Chicken feathers constitute about 5–10% of the weight of the chicken and thus they comprise a significant portion of the ... Read more
