Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming …

Factors promoting fluorine flotation in copper ores. The main factors which promote fluorine recovery into copper concentrate are poor liberation (i.e. the association of fluorine-bearing minerals with valuable sulphide minerals), association with non-sulphide naturally floatable minerals such as talc, and entrainment.

A high pH is important in copper ore processing to maximize this mineral's flotation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.
