Toward Zero Waste Mining: Circular Economy of Copper Slags. [PDF]

open access: yesGlob Chall
Mining and metal extraction processes generate over 90% of global waste. With the rapid increase in population and urbanization, the demand for geotechnical applications and construction materials constantly increases and can absorb the entire quantity of slags generated.

Electrorefining of aluminum alloy in ionic liquids at low temperatures [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2003
The electrorefining of aluminum alloy (A360) in ionic liquids at low temperatures has been investigated. The ionic liquid electrolyte was prepared by mixing anhydrous AlCl3 and 1-Butyl-3- methylimidazolium chloride (BMIC) in appropriate proportions.

Effect of non-stationary current regimes on the morphology of silver electrodeposits [PDF]

open access: yesJournal of the Serbian Chemical Society, 2009
This work is concerned with the use of reverse current regimes in order to form small-grained and compact silver deposits during the electrorefining process. Several parameters were varied, i.e., i) anodic overpotential, ii) cathodic vs.

The Behaviour of Low Arsenic Copper Anodes at High Current Density in Electrorefining [PDF]

open access: yesArchives of Metallurgy and Materials, 2023
Arsenic is the only beneficial impurity for copper electrorefining through inhibiting anode passivation and the formation of floating slimes. The behaviour of copper anodes with different content of arsenic were studied at high current density (>280 A/m ...

Copper Cathode Contamination by Nickel in Copper Electrorefining

open access: yesMetals, 2021
Nickel behavior has a significant role in the electrorefining of copper, and although it has been extensively studied from the anode and electrolyte point of view over the past decades, studies on nickel contamination at the cathode are limited.

Challenges for development of technology for prevention of anode passivation during electrorefining of low-grade copper

open access: yesJournal of MMIJ, 2020
Over the past years, the significance of recycling Cu and its accompanying metals has been increasing. However, the frequency of anode passivation increases during the electrorefining of copper when the copper anode contains a high concentration of ...
