Froth flotation of Aljustrel sulphide complex ore 759 Froth flotation occurs in an aqueous medium which involves aggregation of air bubbles and mineral particles with subsequent levitation of aggregates to the surface and transfer to a froth phase. The degree of particle surface wettability determines attachment and aggregation.
