1 Froth Flotation – Fundamental Principles

2009-8-27 · 1 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

Celanese - The chemistry inside innovation

Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water, and air bubbles.

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. The ores are crushed into very fine powder sized particles and mixed with water.
