  • Publication number: 20220349026
    Abstract: A metal purifying method having: a local heating step of heating an aluminum-based molten metal in a first region on a molten metal surface of the aluminum-based molten metal; and a local low pressure step of lowering the pressure in a second region on the molten metal surface to a pressure lower than the pressure in the first region. The second region is different from the first region. This allows a specific element to be vaporized from the second region to purify the aluminum-based molten metal. The specific element is one or more of Zn, Mg, or Pb having a saturated vapor pressure higher than that of Al. This is effective not only in a purifying method for removing a specific element from an aluminum-based molten metal but also in a method of recovering a specific element, which can be a resource, from an aluminum-based molten metal.
