Flotation

Flotation in mineral processing method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition that is the surfaces are either repelled or attracted by water.The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.
