History – AusIMM celebrating 125 years

The original patents for the flotation process were secured by C. V. Potter in 1901 and by G. D. Delprat in 1902. Controversy over the originality of each soon followed and litigation ensued, lasting until 1907. The Potter - Delprat process, as it was referred to after 1907, proved unsuccessful on a large scale.

Guillaume Delprat – AusIMM celebrating 125 years

Delprat spent many years in Broken Hill and was naturalised in 1904. A method for separating ore from rock crushings using bubbles to float the ore to the surface was developed by Charles Potter and Guillaume Delprat in the early 1900s. It became known as the Potter-Delprat flotation process.

Flotation Developments & Best Practice

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. In general, the minerals which are floated are sulphides of ...

Hill adopted Potter's process and between 1903 and 1905 extracted increased quantities of zinc. However, around 1902, Potter discovered that Guillaume Delprat, general manager of the BHP mine at Broken Hill, had obtained patents for a very sim-ilar process and this led Potter to sue BHP for infringement of both his Vic-

Investigation into the Froth Flotation and Selection of ...

Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.

Froth flotation process ... Potter was unsuccessful in court but the method is now known as the Potter-Delprat process. Further research showed that a number of different chemicals, including eucalyptus oil, could be added to the bath to separate different metals from the waste. The process is still being developed and improved upon.

May 27, 1908· Although B.H.P. won eventually on the grounds that Potter's process lacked utility, it soon adopted his use of sulphuric acid and the method of recovery became known as the Delprat-Potter process. This first large-scale flotation process eventually produced 6 million tonnes of zinc concentrate at Broken Hill.

Working with Potter, Delprat had observed in the laboratory that they could make the zinc sulphide in the tailings dumps attach to gas bubbles and float, thereby effecting a separation. A large scale processing plant was quickly built to put this research into practice and the process worked.
