2017-4-9 Froth flotation process. 1904. process for separating mineral ores. At the end of the 19th century, metal prices had slumped and around every Australian mining town mountains of waste were piling up, much of it still containing valuable metals like zinc. The problem facing Guillaume Delprat was to find a cheap way to reprocess the waste and get ...

1981-1-1 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 ...

2020-6-19 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. In 1905, Minerals Separation Ltd ...

2021-9-12 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 formed by the introduction of acid into the pulp.

Guillaume Daniel Delprat, Engineer Miner (1856-1937)
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.
