Behavior of talc and mica in copper ore flotation
The copper ore sample was obtained from Northparkes Copper & Gold Mine, Australia. This ore was chosen due to its relatively unproblematic flotation characteristics. Such an ore provides a formidable baseline for the identification of the deleterious effects of clays. The chemical assays of the ore sample contains 0.5% Cu, 3.8% Fe, and 0.3% S.

60 Centuries of Copper: The Flotation Process
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...

Copper Mining and Processing: Resources and Glossary
For copper sulfide ore, froth floatation is the first stage in the process of pyrometallurgy, in which air bubbles are introduced into a mixture of finely crushed ore with water and a chemical that aids attachment of the bubbles to the particles of copper, which are recovered as a floating froth.

Froth Flotation Process
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
