Electrorefining of Copper
Electrorefining of Copper 1 Electrorefining – General Introduction In an electrorefining process, the anode is the impure metal and the impurities must be lost during the passage of the metal from the anode to the cathode during electrolysis, ie the electrode reactions are, at the anode: M → Mn+ + neand at the cathode: Mn+ + ne→ MAnode slime samples were collected from the bottom of the electrolytic cells during the electrorefining of copper These samples were sieved through a 20 mm sieve to remove large inclusions of copper and other foreign material present in the slime A representative sample of the feed slime was analysed for Cu, Pb, Sn, Zn, Ni, Fe,PROCESSING OF COPPER ANODESLIMES FOR Anode slime is the insoluble product deposited at the bottom of the electrorefining tank during electrorefining of copper It generally contains Cu, Ni, Se, Te, Ag, Au, platinum group metals (PGM), Pb, Ba, Fe, etc Owing to the presence of valuable metals and metalloids in the anode slime, numerous approaches have been made by the researchers to extract them following pyro, pyrohydro Processing of copper electrorefining anode slime: a review
