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 ...

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.

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 ...

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

Molybdenum Electrorefining in Ionic Liquids

ECS Meeting Abstracts, 2019
Molybdenum is a valuable refractory metal used to harden and protect metal alloys. Additionally, certain nuclear reactors can be used to produce Mo99, a valuable radioactive isotope with important medical applications. To qualify for medical use, the isotope must be isolated in high purity molybdenum.

Selective electrorefining with liquid membranes

AIChE Journal, 1983
AbstractLiquid membranes containing macrocyclic polyethers can be used to electrorefine metals. This purification depends on the selective reaction of the polyether and the metal cation to produce a charged product. The amount of this product is found to be proportional to the square root of the amount of polyester present.
