To Float or Sink: A Brief History of Flotation Milling

Mullen, Idaho used the process on lead-zinc ores in its mill. Because the process was extremely fragile, its use was short-lived. The Idaho mill closed by 1920.14 Froth Flotation The first successful commercial mill using froth flotation was built in 1905 at Broken Hill, Australia, today recognized as the "home of flotation

Flotation - Mineral Processing Metallurgy

Mar 17, 2017  Early in 1909, I did a great deal of work with the Macquisten flotation process and in the installation of the tube-plant of the Morning mill at Mullan, Idaho. This work was followed by a large amount of experimenting on the different kinds of existing flotation processes, the outcome of which was the development of the pneumatic method.

Froth flotation - Wikipedia

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti

The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible. What doesn’t float is called tailings because it goes out the “tail end” of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and re-used.
