Froth Floatation Process Principle The principle of froth floatation is that sulphide ores are preferentially wetted by pine oil whereas the gangue particles are wetted by water Collectors are added to enhance the non wettability of the mineral particles Examples of collectors are pine oil fatty acids and xanthates Froth stabilisers are added to stabilise the froth.Separation techniques froth flotation employs a relatively high gas flow rate under turbulent conditions Next to froth flotation the most useful foam separation technique is precipitate flotation where the species to be separated is first precipitated usually by a change of solution pH and then.

Abstract To achieve selective flotation of mineral particles whether by their removal in a froth or by the less used method of agglomeration specific characteristics of one or of the mineral species present must be adequately developed Provided these produce sufficiently marked differences of behaviour in the presence of air they can then be exploited.Jul 06 2017 Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity (how much they are attracted to water) and is enhanced through the use of surfactants Surfactants are chemicals that act as a wetting agent to attach to particles and increase their attractiveness to air bubbles.
