HistoryPrinciple of OperationScience of FlotationFlotation EquipmentMechanics of FlotationChemicals of FlotationSee AlsoWilliam Haynes in 1869 patented a process for separating sulfide and gangue minerals using oil and called it bulk-oil flotation. The modern froth flotation process was invented in 1901 by C.V Potter in Australia and in 1902 by G.D Delprat in Holland. In the early times, only naturally occurring chemicals such as fatty acids and oils were used as flotation reagents in a large quantity. Since then, the process has been adapted to apply to a wide variety of materials to be separated, and additional collector agent…
