The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.
Feed mass flow rate and copper grade of species considered in the case study. For the superstructure, a flotation plant with six flotation stages was considered: rougher , two scavengers , cleaner scavenger , cleaner , and re cleaner stages .
From plant practice, the treatment of oxide copper and copper cobalt ores is being carried out by the following methods: a) Sulphi disation flotation m ethod, b) The carboxylic / fatty acid ...
form of water based slurry) is transported to the flotation circuit where the copper sulfide ore minerals are concentrated and separated from the nonmineralized material by a series of rougher and cleaner flotation cells, which produce successively higher grade concentrates. This flotation slurry, also
