    Electrolytic Extraction of Copper, Molybdenum and Rhenium

    Electrolytic extraction of copper, molybdenum, and rhenium was conducted successfully at 1500 K using an electrolyte composed of alkaline earth, rare earth, and copper sulfides. The addition of a rare earth metal sulfide component to the electrolyte increased the faradaic efficiency and the recovery/isolation of sulfur as the anodic product.

    Their molten sulfide electrolysis process eliminates sulfur dioxide, a noxious byproduct of traditional copper extraction methods, instead producing pure elemental sulfur. We think that with our technology we could provide these copper wires with less energy consumption and higher productivity, Allanore says.

    Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper. This is similar to the electrolysis that is done in a school lab.
