The invention provides a method for recycling zinc from galvanized residues. The method comprises the steps that after the galvanized residues are molten, heat preservation is carried out, and zinc-aluminum residues and liquid zinc are obtained; the zinc-aluminum residues and the liquid zinc are separated through a siphonic method, and separated liquid zinc and separated zinc-aluminum residues are obtained; and the separated liquid zinc is distilled at constant pressure and then condensed to obtain zinc powder. After the galvanized residues are molten, heat preservation is carried out, the zinc-aluminum residues and the liquid zinc are layered better, the zinc-aluminum residues are located on the upper layer, and the liquid zinc is located on the lower layer; and the liquid zinc on the lower layer is sucked out through the siphonic method, the liquid zinc and the zinc-aluminum residues are separated more thoroughly, the purity of the separated liquid zinc is high, and therefore the zinc powder with high purity can be obtained through an atmospheric distillation method. According to the method for recycling zinc from the galvanized residues, the zinc-aluminum residues and the liquid zinc are separated through the siphonic method, and the method can achieve continuous production; and the zinc powder obtained through preparation is high, distillation is carried out at constant pressure, so that the process is simple, and the method is safer.
