Electrolytic Extraction of Copper, Molybdenum and

2017-7-20  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.
