The invention discloses a copper ore associated molybdenum screening method which comprises the following steps: in a process of performing copper-sulfur separation on copper-sulfur crude concentratecontaining molybdenum minerals obtained in a copper ore roughing process, inhibiting the molybdenum minerals in the copper-sulfur crude concentrate into tailings of the copper-sulfur separation operation, and returning copper minerals in the copper-sulfur separation operation into the copper-sulfur separation operation procedure; performing dehydration and reagent removal on the copper-sulfur separated tailings containing the molybdenum minerals, adding an acid to regulate the pH value of the tailings, adding a sulfur separation reagent and a molybdenum separation reagent, performing sulfur-molybdenum dressing, and obtaining qualified sulfur concentrate containing the molybdenum minerals; performing molybdenum-sulfur separation on the qualified sulfur concentrate containing the molybdenumminerals, adding a sulfur-
