nickel oxides and concentrates

  • Nickel

    Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white 3, while Ni(III) is present in nickel oxide hydroxide, which is used as the cathode in many rechargeable batteries, including First, copper is removed by adding hydrogen sulfide, leaving a concentrate of cobalt and nickel. Then...
