Metallurgy - Definition & Process | Principles of Metallurgy

Froth floatation: The crushed ore is mixed with a mixture of water, pine oil, detergent in a tank to separate sulphide ores. A current of compressed air passes through the pipe of a rotating agitator that produces froth. The presence of differences between the gangue particles and wetting properties of the ore helps to separate them.

Bubbles are formed due to this blown air. A rotating agitator at the centre of the floatation tank agitates the mixture and draws air into it to form bubbles. As a result, foam is formed which carries metal sulphide particles. The foam rises to the surface of water and floats. Therefore, this method is called froth floatation process.

Column Flotation - SGS

The froth of a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a "rain" of water onto the surface of the froth.
