The invention discloses a method for recycling low-grade lead and zinc in pyrite cinder, and belongs to the technical field of ore dressing metallurgy. The method comprises the following steps of: adding pulverized coal and adhesive into the pyrite cinder containing lead and zinc, regulating the moisture, performing wet grinding, pelletizing, drying pellets at a low temperature, performing high-temperature reductive roasting by using gas, collecting dust from the roasting smoke, and thus obtaining lead and zinc mixed concentrate, wherein the roasted pellet ore is an iron-making raw material containing 54 to 60 percent of iron and less than 0.3 percent of lead and zinc. By pelletizing the cinder, carrying out combined reductive roasting with the pulverized coal and the gas and recovering the lead and the zinc from the smoke according to the method, lead and zinc resources which are difficult in lead-zinc-sulfur flotation separation and are greatly lost in the pyrite cinder are efficiently recovered, and the iron resource in the pyrite cinder is also efficiently utilized.
