Method Of Separating Nickel

  • US Patent for Method for separating iron from nickel and .

    A method for separating iron for nickel and/or cadmium contained in a battery waste is composed of a first step in which the spent batteries are crushed and calcined. The calcined pieces are mixed with an acetic acid aqueous solution before acetic acid and water are removed by evaporation or distillation so as to produce a residue containing metallic acetates.
