Abstract: The recent development on flotation electrochemistry of sulphide minerals at Central South University of Technology is briefly summarized. General behavior of natural floatability, self and sulphur induced, and collector induced floatability of sulphide minerals are described. The mechanism is discussed based on Eh pH diagrams, voltammograms, energy band theory and molecular orbital theory.
