Abstract

Sulphide ores constitute the major economic source of nonferrous base metals. The reasons for interest in the electrochemistry of the sulphide minerals in such ores have been dealt with by Peters (1) elsewhere in this volume. Briefly, electrochemical mechanisms underlie many processes of practical importance in metal recovery from sulphides, such as the weathering (2–4) and leaching (5) of the ores and the production of sulphide mineral concentrates by froth flotation (6,7). These involve corrosion-like processes consisting of coupled anodic-cathodic reactions. Reduction of dissolved oxygen is the major cathodic component in certain of these systems, e.g. oxygen pressure leaching, the weathering of ore bodies as a consequence of differential aeration, and flotation with thiol collectors. It is the aim of the work presented here to provide a basis for understanding the chemistry of this reaction.
