1. Introduction. The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).Separation of mineral …

Flotation froth is a process used in the mining industry to physically separate particles based on their ability to adhere to air bubbles. It involves creating a froth containing hydrophobic particles attached to air bubbles, which can then be removed from the liquid phase. ... These smaller cells offer many advantages, not the least of which ...
