ABSTRACT:
A method and apparatus for enhancing reaction rates between ionic species such as slags, mattes, fluxes and the like with at least another component such as similar melts, metals, chemical compounds, gases or any combination thereof during metal processing operations is provided. A dispersion of the ionic species and the other component or components is formed and contacted with a plasma or electric arc such that migration of the ionic species is facilitated and space charges in the ionic species are discharged. Reactions for decarburization, dephosphorization, desulfurization, deoxidation, alloy additions, refining, extractions and recycling processes on an industrial scale are thereby enhanced.
