Froth Flotation Process
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

[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.
Overview of flotation as a wastewater treatment technique
In mineral flotation it is necessary to produce a stable froth at the free surface of the flotation cell. In applications to wastewater treatment an stable is not required. In mineral flotation, the overall process is economically attractive. In environmental application, usually flotation means an extra cost.

This step is known as flotation. Eventually, frothing occurs with the incorporation of air and only the desired minerals or metals levitate to the surface with air bubbles. Separate the froth with a maximum concentration of the desired mineral. List of chemicals used. The process of froth flotation uses various reagents. Most of them are liquid.
Principles of Froth Flotation | SpringerLink
For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth. Random changes of direction, acceleration, and collision ...
