Distillation may be a more appropriate analogy. The unwanted part evaporates away, leaving the more concentrated solution behind.

  In distillation, the whole input liquid is evaporated by heating, then condensed by cooling and collected.

    That depends on whether you want the more volatile or less volatile liquid at the end.
