Units are distinguished as cells of ideal and non-ideal flow. A brief introduction to hydrodynamics is included toDec 29, 2019 Flotation Separation is a way of separating mixtures. It is used to separate substances by whether they float or sink. When a mixture is put into a tube and is stirred, the lighter substance should rise above the heavier substance.Froth flotation is one of these techniques, which is based on hydrophobicity differences between particles. Unlike minerals, most of the plastics are naturally hydrophobic, thus requiring the addition of chemicals that promote the selective wettability of one of its components, for a flotation separation.
