  • Biography Guillaume Daniel Delprat Australian

    Delprat played an important part in the perfecting of a technique that came to be known as the [C.V.] Potter-Delprat flotation process; it revolutionized sulphide ore treatment and brought enormous profits from the metal content of millions of tons [tonnes] of formerly useless tailings. He received from B.H.P. £1000 for his patents and from

    The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp.

  • History of Flotation Patents

    This is the part of the subject of which we have heard the most; indeed, until recently the literature of the flotation process was closely identified with the records of patent litigation. That is why the scientific principles are as yet so little understood and the technology of the process has made such scanty progress. The aim of a patent specification is to disclose just enough to prove

FLOTATION process can be applied to relatively fine particles, because if the particles are coarse and heavy, their weight will be greater than the adhesion between the particle and the

  • Froth_flotation : definition of Froth_flotation and

    Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible.

    History. William 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.
