  • The treatment of copper refinery anode slimes | SpringerLink

    There are numerous viable approaches to the treatment of anode slimes from electrolytic copper refining. Of particular interest in the treatment of slimes are the behavior and recovery of selenium. The understanding of the process chemistry involved in the treatment of anode slimes should be aided considerably by recent work on the formation and characterization of slimes. .

  • : Refining of Copper

    The electrolyte is a solution of copper (II) sulfate. Some of the impurities are metals such as Fe and Zn which are more easily oxidized than Cu. When current passes through the cell, these impurities go into solution from the anode, along with Cu: Cu ( s) → Cu 2 + ( a q) + 2 e − Fe ( s) → Fe 2 + ( a q) + 2 e − Zn ( s) → Zn 2 + ( a q) + 2 e −

  • During the purifiion of copper by electrolysis?

     · Why is electrolysis used in the extraction of copper? Copper is well below carbon (less reactive) and so can be displaced by carbon from its compounds eg copper oxides or sulfides. However, in practice, modern copper smelters can actually manage the extraction without using carbon (coke) and then electrolysis is usually used to purify the impure copper .
