A device and process that broadens the commercial and industrial applicability of metal extraction from ore by utilizing a novel substance as an electrolyte. The process overcomes the technical limitations of conventional electrolytic processes. A monatomic substance is used to create an electrolyte that avoids degradation, improves process kinetics, and minimizes end-product contamination. The electrolyte enables an electrochemical process at a lower operating temperature, offers a wider electrochemical potential window, and runs at higher reaction rates than either molten or aqueous processes. The device comprises a reactor, an electrochemical cell, a means for generating electromagnetic radiation, and a waveguide. The electrochemical cell is located within the reactor, and the means for generating electromagnetic radiation is coupled to the waveguide, and the waveguide is communicatively coupled to the reactor.
