The significance of frothers in the context of mineral flotation is widely recognized, particularly in relation to their impact on bubble size and dispersion, coalescence inhibition, as well as the structure and stability of the froth. ... In a flotation cell, the size of air bubbles decreases with increasing the frother concentration. This is ...
Flotation
The bubbles of air, sucked or blown into the pulp in the flotation machines, become coated with mineral and rise to the surface where they collect in the form of a mineralized froth. This primary concentrate, in which the bulk of the mineral is collected, continuously flows or is scraped over the lip of the machine into a collecting launder.
