The invention provides a method for recovering iron and zinc from copper tailing slag. The method comprises the following steps: the copper tailing slag, reduced coals, limestone, bentonite and NCP are mixed by a powerful mixer through an adhesive tape machine and a liquid bonding agent in a burdening chamber for pelletizing and screening; green balls are dried to enter a pre-reduction furnace; part of tailings are reduced to enter an iron making furnace; materials are continuously heated for melting to reduce such oxides as zinc oxide and iron oxide; reduced zinc is fed in a smoke system in asteam form; smoke is collected to obtain zinc oxide dust; cast iron blocks are discharged in a molten state from reduced iron in the iron making furnace; and metal iron blocks of steel making raw materials are obtained through recovery. The method has the following advantages: the recovery of iron and zinc resources in the copper tailing slag is realized; wastes are changed to valuable things; the problems of land occupation by copper tailing slag stacks and environmental protection are reduced; the industrial chain in the nonferrous copper smelting industry is improved; the economical valueand the social value of the tailing slag are improved; and active meanings are achieved on environmental protection and comprehensive utilization of resources.
