Natural Chalcopyrite

Anodic oxidation of the natural mineral chalcopyrite from the Bor ore deposit has been studied by cyclic voltammetry in pure sulfuric acid solutions. At the obtained voltammograms, the appearance of peaks at certain potential regions was identified and found to be much less pronounced than those previously reported in the literature. The voltammetric kinetic analysis confirmed that two-electron exchange electrochemical reactions occur. The explanation for this somewhat different electrochemical behavior of natural chalcopyrite compared to the concentrates widely used in studies of this mineral will also be given.
