    How do you separate metal alloys into their constituent elements, especially industrially? I don't think you can always use melting points, because alloys, depending on the composition (looking at phase curves) can have one common melting point. Here's a phase diagram for a copper-nickel alloy, which I think is a system where both components are completely soluble in one another in all ratios
