The gypsum produced from flue gas desulphurisation (FGD) can dissolve in the solution and release calcium ions. FGD gypsum also has an adsorption ability for heavy metal ions [15], thus, it maybe is a feasible choice for wastewater treatment. FGD gypsum is produced from the process of wet limestone flue gas desulfurization.

The main impurity mineral in the raw PG was quartz. Flotation is an effective method to separate quartz and gypsum, but the quartz needs to be effectively inhibited in the flotation process (Xiao et al., 2022; Zhang et al., 2022). The desilication flotation tests were implemented with the slurry pH in the range of 2–2.5.
