(Purpose) High-quality, high-quality recycled zinc that can be reused in the hot dip galvanizing process from pure zinc, compounds, and oxides contained in dross produced during hot dip galvanizing at low processing costs, short processing times, and high recovery rates. It aims at efficiently separating and recovering.;(Composition) Melting point of each component contained in the dross by putting the dross generated in the hot dip galvanizing into a large-capacity reflection furnace and heating and melting it with a gas burner at 550 to 700 ° C., and simultaneously performing mechanical stirring using a stirrer. And separating the impurity-containing layer such as Al + Fe compound and the high-purity zinc layer by the decomposition temperature difference and specific gravity difference, and then removing the impurity layer on the top first, and adding Al to adjust the component. Dross remelting specific gravity separation method characterized in that it is maintained for 50 to 70 minutes to precipitate the free Fe and Pb components, etc. present in the liquid phase, and tapping the recycled zinc through the regeneration zinc tap in the bottom of the furnace.
