Ground ore is directed to a series of froth flotation cells in which hydrophobic copper sulfides and other minerals attach to bubbles where they form a froth that is skimmed off..28 Figure 5 Copper anode arrives at a refinery for electrorefining ..41 Figure 6 Photograph of electrolytic cells in a copper refinery ..42 Figure 7 A photograph of the Cripple Creek Victor Mining

1 Froth Flotation Fundamental Principles

While this data is available in laboratory experiments in the plant it is likely that the ore is not weighed and only assays will be available However it is possible to express the ratio of concentration in terms of ore assays Starting with the mass balance equations and the definition of the ratio of concentration F = C T Ff = Cc Tt Ratio of Concentration = F/C where F C and T
