The invention relates to the field of mineral flotation separation processes and hydrometallurgical technology, in particular to a method for recovering valuable components from sulfur-oxygen mixed copper and lead ore. The method includes the steps of flotation pulp preparation, primary roughing, secondary roughing, third to sixth roughing and mixed concentration, separation between copper minerals and lead minerals, copper recovering from flotation lead concentrate, and the like. The method has the beneficial effects that multi-stage mixed flotation of the sulfur-oxygen copper and lead minerals is conducted in a weak alkali and weak calcium medium, separation between the copper minerals and the lead minerals is conducted under the conditions of high alkali and high calcium, the lead concentrate is further treated with acid mine wastewater, and thus the problems that by the adoption of a traditional separation method, the resource recovery rate is low, environmental pollution is severe, and reagent cost is hi
