Many copper refineries that are embracing 'zero discharge' are abandoning evaporization and crystallization, electing instead for an Acid Purification Unit (APU) to treat the decopperized nickel solution using ion exchange to recover the sulfuric acid and produce a de-acidified nickel solution.
Cu-Ni alloys do not exhibit any ferromagnetism. Copper is diamagnetic, nickel is ferromagnetic. Nickel-copper alloys change from diamagnetic via paramagnetic to ferromagnetic as nickel content increases. Depending on the alloy, iron has a small effect when it is present in solid solution.
Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
