Electrowinning and Electrorefining

Many high-purity nonferrous metals are produced by electrolysis in processes commonly called electrowinning or electrorefining. Electrowinning involves the winning or recovery of dissolved metal from solution by electrodeposition of solid metal ...

Electrorefining of metallic fuel with burn-up of ~7 at% in a LiCl-KCl melt

Journal of Nuclear Science and Technology, 2018
Electrorefining of irradiated metallic fuels (burn-up ~ 7 at%) in a LiCl-KCl melt at 773 K was successfully demonstrated: Actinides in the fuels were anodically dissolved in the melt.

Electrorefining for direct decarburization of molten iron

Nature Materials, 2021
Recycling iron and steel is critical for environmental sustainability and essential to close material loops in circular economics. A major challenge is to produce high-value products and to control impurities like carbon in the face of stringent consumer requirements and volatile markets.

Direct electrorefining of chalcocite

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1981
Abstract Massive specimens of the mineral chalcocite (Cu2S), when subjected to anodic decomposition in copper refinery electrolyte (CuSO4−H2SO4) increase in potential abruptly at a transition time τ, the value of τ having a dependence on current density as defined by the equation I2τ=constant This constant is typically 2.5×108A2sec m−4, in 0.1M ...

Purification of gadolinium by electrorefining

Metallurgical Transactions B, 1978
The electropurification of crude gadolinium, as an alternate method to the distillation process currently used, was studied using a LiCl−LiF−GdF3 electrolyte. The best results were obtained with a 77.6 wt pct LiCl, 11.2 wt pct LiF, 11.2 wt pct GdF3 electrolyte at 700°C. It was shown that the purity of the deposit was strongly dependent on the purity of

The mineralogy of copper electrorefining

JOM, 1990
The impurities in copper anodes occur both in solid solution in the copper metal matrix and in discrete inclusions at the copper grain boundaries. During electrorefining, all the impurities undergo extensive chemical and/or morphological changes. These changes impact significantly on anode passivation, cathode quality, electrolyte purification and, of ...
