The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance ...

Flowsheet for treatment of Copper Sulfide ores rich inminerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper.

Flotation plant recovery: a copper flotation plant, fed with Cu–Pb concentrates, produces a copper concentrate and a tail which is subsequently fed to a bulk flotation plant delivering a lead concentrate and a zinc-lead concentrate [14]. The traditional 2-product formula can be used to calculate the recoveries from the raw data.

The flotation kinetic model parameters are derived from continuous plant sampling data or from batch laboratory tests. Figure 1 shows the Outotec GTK LabCell laboratory flotation machine for batch testing. The outcome of a kinetic batch flotation test is a series of cumulative recoveries of assayed elements as a function of time.

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons …
