Zusammenfassung:	Provided is a technique for resource utilization of lead and silver residues for zinc hydrometallurgy. The technique comprises the steps that the dried lead and silver residues, lead concentrate and additives are blended, so that a mixture is obtained; the mixture is fed to an oxygen-enriched bottom-blowing furnace for oxidation smelting after being subjected to granulation, and primary lead and furnace residues are separated out; the furnace residues are fed into an oxygen lateral blowing metal smelting reduction furnace, broken coal and a flux are added to the oxygen lateral blowing metal smelting reduction furnace, so that furnace residues of the oxygen lateral blowing metal smelting reduction furnace are formed; the furnace residues are fed into a fuming furnace to obtain secondary lead; as for silver entering the primary lead and the secondary lead, anode mud is added in the electrolytic lead refining process of the primary lead and the secondary lead, and the silver is extracted from the anode mud; and
