Mineral Dressing Process: Separation Operation
The separation operation is the critical operation (or main operation) of the beneficiation process. It adopts different beneficiation methods according to the other properties of minerals. Separation operations include gravity separation, flotation, magnetic separation, electric separation, picking selection, and chemical beneficiation.

Solubility of copper in molten aluminum is about 5%, but lead and tin can absorb a lot more, so melting one metal and leaving the other intact can be a challenge. you could make an alloy that is harder to separate. E.g.: when you melt lead with gold, the gold will go in solution at around 300C in stead of its melting temp of about 1000C !!
