Abstract

Provided is a metal recovery method in which, after pouring molten iron from a ladle (6) into a converter, metal (6b) that has adhered to the ladle (6) is dropped into the ladle (6) while said ladle is on the production line, and molten iron from an electric furnace is poured on the ladle (6) into which the metal (6b) has been dropped so that the metal (6b) is dissolved and recovered for use as material.
