Copper Flotation Mineral Processing & Metallurgy

2016-5-16  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.

2003-11-1  The grinding conditions affect significantly the subsequent flotation stage of this sulphide copper ore. The presence of iron ions in the slurry is deleterious to the flotation of copper minerals and may be avoided by the utilisation of lined mills and non-ferrous or corrosion resistant grinding media, such as stainless steel or pebbles.

Effect of grinding time on flotation recovery of copper

Copper smelting slags are hard materials. Therefore,to recover their copper by flotation method, grinding should be carried out to obtain optimal particle size. Copper smelting slags in the Bardeskan district, with work index of 16.24 kwh/st, were grinded for 65 minutes to reach an acceptable degree of freedom for the flotation tests, with particle size of 80%, smaller than 70 μm.
