Abstract

Raman spectroscopy has been a useful technology for fundamental studies in the mining industry. Surface changes through oxidation and reduction reactions can be monitored in-situ, allowing the changes to be monitored in real time. In conjunction with cyclic voltammetry, to change the conditions at which a mineral surface is subjected to, reaction and reaction conditions can be identified. The results can then be plotted to create a map similar to that of an EH-pH diagram.
