Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

Flotation Mineral Processing & Metallurgy. The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process …
Flotation is widely used to separate valuable minerals from the rock and fine coal particles from clay, silt, shale, and other ash-producing matter. It is usually preceded by crushing and finely grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.
Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations ...
