[PDF] Froth Flotation – Fundamental Principles
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay in the liquid phase. …

Recovering Gold through the Froth Flotation Process
Along with mechanized mining equipment, froth flotation dramatically improved the efficiency of gold mines. Thanks to this process, miners and refiners are able to extract quality minerals from ore at lower grades than has been previously possible – making it perhaps the most important mining industry innovation of the 20th century.

Explaining the Process of Froth Flotation
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …
