The invention discloses a clean production method of copper smelting smoke and a lead-containing secondary material, and aims to provide a method for smelting smoke using copper and smelting lead using the lead-containing secondary material. The clean production method comprises the steps that silicon, calcium-containing oxide materials, iron-containing oxides and binders are added to copper smelting smoke and/or the lead-containing secondary material and are batched in batches; water is added and the materials are mixed to form a material with a certain shape; and after the material is stacked to solidify and harden, the material is mixed with coke to complete preheating, reduction, smelting and separation in a blast smelting furnace, and metals are recovered in layers. The clean production method uses the principle of preferential formation of copper matte between sulfur and copper without using sintering desulfurization and molten pool smelting conditions, and reaction characteristics of SiO2 with slag, copper matte, and iron oxide during the smelting process. Slag type is adjusted to overcome harmful effects of copper, sulfur, and arsenic on the production process in traditional lead smelting, and the goal of effectively separating and recovering copper, lead, arsenic, sulfur and other metals is achieved. Not only can the problem of environmental protection in the lead smelting process be solved, but also the overall economic benefits of production can be improved.
