Flotation is a process that separates hydrophilic particles from hydrophobic particles by means of air bubbles that rise to the top of a flotation cell to produce a froth layer (Wills & Finch, 2016). Ideally, hydrophilic particles remain in the pulp phase and hydrophobic particles adhere to air bubbles and exit
