The invention belongs to the technical field of treatment of cyanidation tailings, and particularly relates to a comprehensive utilization method of cyanidation tailings in a dangerous waste smelting process. The comprehensive utilization method comprises the following steps: carrying out high-temperature drying on the cyanidation tailings, mixing the dried cyanidation tailings and copper-containing dangerous waste materials, drying the obtained mixture, then pressing bricks, and drying the pressed bricks again, the dried bricks, coke and a flux are mixed and then smelted, gold, silver and copper in the bricks are reduced to obtain matte cast ingots, obtained molten slag is subjected to water quenching, obtained water-quenched slag and metal lead and metal zinc steam obtained through reduction in the smelting process are oxidized through hot air, and lead oxide and zinc oxide are obtained. By means of the comprehensive utilization method, full utilization of the copper-containing dangerous waste materials and the cyanidation tailings can be achieved, gold, silver, copper, lead and zinc in the waste materials can be efficiently recycled, and environmental pollution caused by mass discharge and stockpiling of the gold cyanidation tailings and the copper-containing dangerous waste materials is solved.
