SOURCES OF GYPSUM IN SOUTH AFRICA Agrispex
The main sources of PG in South Africa are located in Modderfontein, Phokeng, Potchefstroom and Phalaborwa which are reported to carry in excess of 15 million tons. Other sources of gypsum are produced from flue gas desulphurization (FGD) in industrial processes in which Sulphur Dioxide (SO 2 ) is scrubbed to meet SO 2 emission standards.
