When is flotation method used? Explained by FAQ Blog

Froth flotation works by exploiting the hydrophobic properties of gold molecules. ... Aided by the surfactant, the water repels the gold into the air bubbles, which rise to the top - creating a bubbly golden froth. The froth is skimmed from the surface and collected and later condensed into metallic gold.

What is froth flotation and what are its applications? - Quora

Froth flotation is the process of selectively collect the hydrophobic material (water-hating) from the hydrophillic (water-loving) one. The process works by bubbling air through a slurry. The hydrophobic particles that don't want to stay in water will attach themselves to the air bubbles and get carried out of the slurry.
