The invention belongs to the technical field of colored metal smelting, and particularly relates to a method for improving comprehensive utilization of the complex colored heavy metal resources. An interdisciplinarity comprehensive method of hydrometallurgy, solution chemistry, organic solvent extraction chemistry and physical chemistry of metallurgy is adopted to analyze the leaching process of copper-lead-zinc-silver complex polymetallic ore containing tetrahedrite, process parameters of the smelting process are determined and optimized, and a process of comprehensively recovering copper, lead, zinc and silver is established. The conventional hydrometallurgy and a reinforced leaching means are adopted to leach the ore, an existing mature wet-method smelting technology is used for recovering metal, the whole technological process is a full-wet-method process, arsenic and other harmful components do not enter the air, and pollution to the air environment cannot be caused. The leaching process dynamic theory of the copper-lead-zinc-silver complex polymetallic ore is established; the comprehensive smelting and recovering process for the copper-lead-zinc-silver complex polymetallic ore is established; and the leaching rate of copper, lead, zinc and silver is 95 % or above, and a basis can be provided for actual production.
