• How can I seperate copper from nickel ResearchGate

    All Answers ( 8) In the end, you can recover the metals by means of crushing, grinding, flotation and magnetic separation. Besides, leaching one or two metals from the matte also can be used to separate the copper and nickel. Acid leaching can dissolve and separate out copper while oxidizing the matte can be used to leach our nickel.

  • inorganic chemistry Separating nickel coin into copper

    To separate the copper, I would suggest that you shake the copper / nickel mixture in hydrochloric acid with 30 % aliquat 336 diluted with aromatic kerosene (or ethyl benzene). Do this in a fume hood. The copper will be extracted by this solution of an ionic liquid in the aromatic solvent and the nickel will be left behind in the aqueous solution.
