The direct electrorefining of copper matte SpringerLink

Direct electrorefining of copper matte would be a desirable alternative to copper converting and its associated troublesome sulfur dioxide emissions After more than 100 years of study however no commercial process has been developed even though an analogous process for the direct electrorefining of nickel matte anodes has been operating

Electrolytic Copper Refining Plant metal recycling machines

As current is passed through the solution pure copper from the anodes is plated out onto pure copper cathodes and the foreign metals accumulate as “anode sludge” in the bottom of the anode compartment of the electrorefining cell The oxidation of copper is more facile than the oxidation of water so metallic copper dissolves into solution
