Foaming In Ore Flotation

Bubble And Foam Separations Ore Flotation

In contrast to froth flotation, foam seon techniques generally use low aeration rates without any intense agitation. Foam containing the colligend, called foamate, is collected by suction or overflow and then is broken by chemical, mechanical, or thermal methods.s A schematic diagram of a typical foam separation unit is given in Fig. 16.2-3.
