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.
Apr 13, 2021· 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.
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 ...
Another flotation process was independently invented in the early 1900s in Australia by Charles Vincent Potter and around the same time by Guillaume Daniel Delprat. This process (developed circa 1902) did not use oil, but relied upon flotation by the generation of gas formed by the introduction of acid into the pulp. In 1902, Froment combined ...
Invention of the flotation vessel 1902. Inspired partly by brewing techniques, the Potter-Delprat Process is developed by BHP to extract huge tonnages of zinc that were not previously commercially viable. Modern versions of this flotation process are used around the world to extract a …
Jan 30, 2013· Froth flotation process: The process of separating minerals from rock by flotation was developed by Charles Potter and Guillaume Delprat of New South Wales. In 1905 Anthony Mitchell invented the tilt-pad thrust bearing which revolutionised thrust technology, whatever any of that means.
May 02, 2004· 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.
Mar 27, 2016· 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 ...
process was the Potter-Delprat process (Figure 3a) used at Broken Hill (Truscott 1923; BHP 2015). As with one of the Bessel patents, it relied on the generation of carbon dioxide gas from the reaction of acid with carbonates. The feed material naturally contained carbonates and therefore only the acid needed to be added (Truscott 1923).
The first commercially successful froth flotation process for sulfide minerals was the Potter-Delprat Process, which was first used (and not used much elsewhere because better processes. Page 90 Share Cite. Suggested Citation:"3 Availability and Reliability of Supply." National Research Council.
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-
A brief outline of some of the pioneering events in the development of flotation technology, which originated in Broken Hill at the start of the 1900s, is presented. The development of the original Potter–Delprat process, the introduction of oils to generate froth flotation and the achievement of selective flotation processing are described ...

Another flotation process was independently invented in the early 1900s in Australia by Charles Vincent Potter and around the same time by Guillaume Daniel Delprat. [7] [8] This process (developed circa 1902) did not use oil, but relied upon flotation by the generation of gas …
Sep 10, 2011· The reality of such a mechanism is confirmed by the multiyear practice of applying the Potter-Delprat process. In connection with the aforesaid, when investigating the flotation process, it is more rational not to orient for the principle of "effective collisions" of particles and bubbles as a necessary condition for their adherence and ...

Two examples of Australian contributions illustrate this point—the development of flotation technology by Potter, Delprat, and de Bavay and Imperial Chemical Industries (ICI) Australia's contribution jointly with Cook-Farnham, Canadian Industries Limited (CIL) of Canada, and ICI U.K. to the large-scale development of ammonium nitrate ...
Mar 11, 2016· Flotation Principles. Flotation, in its latest phase, is a process of concentrating ores by frothing. When crushed ore, previously mixed with water and a relatively minute addition of oil, is agitated violently in the presence of air, a froth is formed. This froth, rising to the surface of the liquid mixture, is laden with sulphides or other ...

Chemical engineering problems often contain only one or two phases, but here there are solid, liquid and gas with generally a large number of solid phases.

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.
