- Copper Ore Flotation Machine Copper Ore Flotation
Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste.

The copper ore flotation method can be divided into forward flotation and reverse flotation according to the separation of valuable components: discharging useless minerals (gangue minerals) in the slurry as tailings are called forward flotation. Otherwise, it is called anti-flotation. Copper is one of the important non-ferrous metals. In the production …

Porphyry copper deposits are important sources of copper and typically processed by flotation to produce copper concentrates. As mining areas become deeper, the amounts of impurities, such as sphalerite, can be increased in copper ores, so the appropriate depression of sphalerite floatability should be achieved to obtain saleable copper …

Fig. 1, Fig. 2 show flotation results obtained with two different chalcopyritic Cu–Mo ore samples floated in fresh water and sea water. Molybdenite flotation in sea water was depressed in alkaline solutions when pH was higher than 9.0–9.5. At the same time, Cu recovery was only slightly reduced and was not significantly affected by pH.
