Simulation Analysis of Potential Distribution, Ion Concentration Distribution and Natural Convection in Electrolyte During Copper Electrorefining

Journal of MMIJ
Numerical simulations are widely used to analyze the mass transfer in a cell with the aim of improving the efficiency of electrolysis processes. In this study, galvanostatic electrolysis with CuSO4–H2SO4 aqueous solution as the electrolyte and pure ...

The Effect of Lead in Copper Electrorefining

To meet the rising copper demand, the industry decides to recycle secondary copper sources for copper production. It results in more impurities including lead appearing in the electrorefining process at the end of the copper production process. There are

Pseudo-Closed-Loop Metallurgy and Quality-Adjusted Circularity of Secondary Copper: A Conceptual Framework

Metals
Mass-based circularity indicators, such as ISO 59020:2024, quantify material recovery as a share of total throughput but do not account for chemical composition or functional performance, as a consequence of their sector-agnostic design.
