Abstract
A process for removing non-ferrous metal, such as Cu, Sn, Zn or the like, from solid ferrous scrap, which includes the steps of: admixing solid ferrous scrap containing non-ferrous metal with liquid Al, Mg, and or alloys thereof comprising at least 20 wt. % in total of Al and/or Mg at a temperature of higher than the melting point of the liquid metal and lower than the melting point of Fe; and separating said solid ferrous scrap from said molten metal. The non-ferrous metals in contact with the liquid metal at high temperatures are efficiently dissolved into the liquid metal and transferred from the scrap to the liquid metal. The resulting ferrous scrap is suitable as a Fe source for electric-furnace steelmaking.
