minerals can be naturally hydrophobic or made so by the addition of chemicals. This process is called Flotation and is used extensively in the mineral industry. It is carried out in Flotation Cells which are large tanks made in a wide range of shapes and sizes. A common form is a rectangular tank with a central impeller for stirring the slurry
