Froth flotation: a quick overview

 · Froth flotation represents the most versatile separation method in mineral processing. It takes advantage of the different surface minerals properties to selectively separate more hydrophobic minerals from less ones towards interactions with air bubbles. Flotation has been initially developed to treat the sulfide minerals of copper, lead, and zinc.

Froth Flotation and Gold Extraction

 · Most methods of water-based gold extraction are dependent on gold''s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
