ABSTRACT
A number of approaches can be used to study pyrite oxidation. They include inorganic/biochemical reaction approaches, electrochemical reaction approaches and reaction kinetics approaches. Each of these approaches may reveal some information with respect to pyrite oxidation, but all approaches are to some degree interrelated on interdependent. Thus, the study of pyrite oxidation is a rather complex process because one cannot separate kinetic processes from electric processes and/or from chemical processes, inorganic or biological in nature. Classical chemistry tells us that an atom, of any given element, is made-up of neutrons, protons and electrons. The processes controlling pyrite oxidation requires understanding of the basic principles of redox chemistry and the parameters affecting/quantifying redox, for example, Redox potential (Eh), pH. Eh measurements are commonly made with a platinum electrode and a calomel reference electrode connected to a volt meter. In general, most electronic pH meters are capable of measuring Eh.
