Abstract
The common sulphide mineral pyrrhotite (Fe(1-x)S) occurs in varying crystallographic forms with each type exhibiting subtly different physical and chemical properties. Accounts in the literature suggest that the processing behaviour of magnetic and non-magnetic pyrrhotite differ from each other in their flotation properties, although limited agreement exists in terms of which is the more reactive pyrrhotite form. Since the flotation process is based on the surface properties of the sulphide minerals and pyrrhotite is a metallic conductor, it is of interest to characterise the surface properties of pyrrhotite with respect to its electrochemical state.
