What Is Froth Flotation

The frothers most widely used in froth flotation operations are compounds containing a non polar water repellant group and a single polar water avid group such as hydroxyl (OH) Typical of this class of frothers are mixed amyl alcohols methylisobutyl carbinol.Flotation frothers also known as flotation foaming agent is an essential flotation agent for froth flotation The role of flotation frothers is mainly to produce a large amount of foam in the pulp so that the available minerals are effectively enriched at the interface between air and water to create the conditions required for flotation process The quality of flotation frothers directly.

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.Aug 15 2020 1 Introduction The gravity and dense medium separation processes are widely used for beneficiating coarse coal particles (+500 μm) while the froth flotation is the most efficient process for cleaning fine coal (−500 μm) (Laskowski 2001) Flotation columns are superior to conventional mechanical cells in cleaning fine coal because of having a deeper froth as well as a froth washing.
