Flotation, or froth flotation, in a separation process used mainly in the mining industry. It's basis of operation is to selectively separate hydrophobic materials from hydrophilic ones using air bubbles injected into a slurry holding finely ground ores. Additives added to the mix make the desired ore particles 'stick' to the bubbles, while the non desirable mineral particles sink to the bottom. The separated ores attached to the bubbles are skimmed off for further processing.
Additives can act as collectors, frothers and modifiers.
The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.
The collected ores are called the concentrate, while the separated gangue is the tailings.

Ores are generally included in a part of a mother rock called the gangue

 Ores are generally included as part of a mother rock called the gangue.  Mechanical crushing and milling break the rock down into fine powders where the individual ore particles are separate from, but still tightly mixed with, the surrounding minerals.  Flotation is one of the methods used to separate the crushed ores from the gangue.
