The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

One way to overcome the complex problem of increasing demand for metals coupled with rapid depletion high-grade raw materials is boost research into innovative methods metal recovery. Electrochemical recovery production has already gained ground in electrowinning and electrorefining Cu, Zn, Au, example, from highly concentrated purified hydrometallurgical solutions. Since 2015, an electrochemic...

Antimony and arsenic concentrations their oxidation states (Sb(III), Sb(V), As(III) As(V)) in copper electrorefining electrolyte can affect cathode quality through the formation of floating slimes. A laboratory-scale pilot plant was operated to remove Sb from commercial electrolyte. The consisted a pre-treatment process with shavings followed by ion exchange. results indicated that Sb(III) remo...

To produce high-purity Al from Al–Cu alloys, the dissolution behaviors of various binary alloy anodes in EmImCl–AlCl 3 ionic liquid have been investigated at 323 K. In anodic polarization measurements, current density peaks were observed potentials approximately 0.3 and 0.8 V vs Al/Al(III) for Al–5.0%Cu casting alloy. constant potential electrolysis cold-rolled plate V, atoms matrix phase prefe...
