Abstract
A method with which Mg can be removed from aluminum alloy melt whose raw material is scrap or the like. Metal removal method includes processing step of forming molten salt layer in contact with aluminum alloy melt containing Mg which covers at least part of the surface of the aluminum alloy melt. This method allows Mg to be taken in from aluminum alloy melt to molten salt layer and removed. Molten salt layer contains specific halogen element that is one or more of Cl or Br and specific metal element that is one or more of Cu, Zn, or Mn. The specific metal element is supplied as an oxide of the specific metal element to the molten salt layer. At that time, the molten salt layer contains Mg. The step of removing Mg is performed by disposing a conductor that bridges the aluminum alloy melt and the molten salt layer.
