The objective of this study was to investigate the floatability of a complex Kansanshi mixed copper ore with a special focus on the sulphidisation process. Controlled potential sulphidisation (CPS) is preferred over slug sulphidisation as the industry standard for the flotation of oxide copper minerals. Two potential ranges were investigated in ...

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 LPF Leach Precipitation and Flotation Process
Precipitation of the copper is completed in about 10-15 minutes. The oxidation-reduction reaction between copper sulphate and metallic iron increases the pH of the pulp to about 3.5-4.0. The copper is precipitated as a very fine copper sponge. An excess of the sponge iron is used so that re – solution of copper is avoided.
