    The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G.D Delprat. Initially, naturally occurring chemicals such as fatty acids and oils were used as flotation reagents in a large quantity to increase the hydrophobicity of the valuable minerals. Since then, the ...

    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.
