ABSTRACT. Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO 2 to produce gypsum (CaSO 2 O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind highgrade limestone (96% CaCO 3) to 95% passing 45 µm prior to use in the FGD scrubber.
