Copper-Nickel Alloys: Properties, Processing, Applications

    Copper and nickel are adjacent to one another in the periodic system of elements, with atomic numbers 29 and 28 and atomic weights 63.54 and 68.71.The two elements are closely related and are completely miscible in both the liquid and solid state. Cu-Ni alloys crystallise over the whole concentration range in a face-centred cubic lattice.

    Copper & Nickel Solvent Extraction

    Nickel-Copper Separation. The ability of nickel to strip from the LIX 64N solvent at relatively weak acid concentrations, while copper stripping must be accomplished at relatively high acid concentrations, serves as the separation route in this study. The stripping characteristics of nickel and copper from LIX 64N were mentioned by Merigold and ...
