flotation process | Infoplease

When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface. The waste material (gangue) settles to the bottom. The froth is skimmed off, and the water and chemicals are distilled or otherwise removed, leaving a clean concentrate. The process, also called the froth-flotation process ...

Entrainment of Gangue Minerals in Froth Flotation

The flotation process is based on the difference in wettability of particles. Hydrophobic particles enter into froth product, while hydrophilic particles remain in the flotation pulp. When the hydrophobic minerals are the gangue minerals, the process is called "reverse flotation"; otherwise, it is simply called flotation.

Flotation is known as a separation process, based on the introduction of gas bubbles as the transport medium. Suspended particulate matter, being hydrophobic or conditioned to be so, is then attach to the bubbles and moves toward the water solution surface—i.e., contrary to the direction of gravity [1,2].Different bubble generation …

Flotation

The flotation process is performed using flotation cells, which are usually grouped into banks. This equipment is interconnected in predetermined arrangements that allow the outputs of the systems to be divided into metal concentrate and tailing flows. Because the desired separation cannot be achieved in a single stage (bank), various coupled ...
