Flotation Froth - an overview | ScienceDirect Topics

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely .

Copper extraction - Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.

Gold and silver metallurgist - Home

Gold losses in copper concentrating are about the same as for copper, but are negligible in smelting and refining. Gold occurring in pyrite associated with chalco-pyrite can sometimes be separated by flotation into an auriferous pyritic concentrate for cyanidation as at Benguet Exploration.
