Extraction of copper by electrolysis

Nov 30, 2019 The electrolytic extraction of liquid copper at 1105 C from a molten sulfide electrolyte composed of 57 wt% BaS and 43 wt% Cu 2 S was investigated. DC cyclic voltammetry, Fourier transformed AC voltammetry, and galvanostatic electrolysis revealed that the electrodeposition of copper is possible in the selected molten sulfide electrolyte

    DOE funds one-step copper extraction Featured

    In June 2017, researchers in Allanore’s lab identified how to selectively separate pure copper and other metallic elements from sulfide mineral ore in one step. Their molten sulfide electrolysis process eliminates sulfur dioxide, a noxious byproduct of traditional copper extraction methods, instead producing pure elemental sulfur

    Procedure for copper chloride aqueous electrolysis

    The electrolysis of copper chloride has three main requirements: (1) separate chambers for extraction of anodic and cathodic products, in order to avoid toxic effects of chlorine in the working area; (2) maximum current density and compactness on the cell, to minimize the investment costs; and (3) a high purity catholyte, to prevent deposition

    Electrolytic Refining - Meaning, Electrorefining of Copper

    Electrolytic refining is a process of refining a metal (mainly copper) by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode. In this setup, an electrolyte (metal salt aqueous solution
