  • Why is CuSO4 used as electrolyte while purifying copper?

    Why is CuSO4 used as electrolyte while purifying copper? , During the electrolytic purification of copper, the electrolyte is taken as copper(II) sulphate ($\ce{CuSO_4}$) Is there any particular reason for this? Could another salt of copper, say $\ce{CuCl_2}$ work?.

  • Electrolytic refining of copper - GoldRefiningWiki

    Copper is refined via electrolysis where an impure copper anode is slowly dissolved while on the cathode very pure copper is deposited Impurities in the copper that is more reactive than copper like zinc or nickel is dissolved while precious metals like gold, silver and PGM:s falls of and creates an anode slime Some other metals will also end up in the slime, as tin, selenium and tellurium.
