The chemistry of flotation activation and depression

The activation process in acidic media is essentially an electrochemical one. Sulphide activation by Cu(II) results in a sulphur-rich copper sulphide surface. In alkaline media, activation proceeds by a surface precipitation. The quantity of copper(II) adsorbed by the sulphides depends on the solution pH, Cu(II) concentration and oxygen content.
