description The invention discloses a method for efficiently oxidizing molybdenite in a sulfuric acid and ferric sulfate solution under a normal pressure condition, which comprises the following steps of: adding trace iodide ions into a sulfuric acid-ferric sulfate mixed solution under the normal pressure condition by utilizing the chemical catalysis characteristic of iodide ions/iodine elementary substances; according to the method, the problem that a passive film is compact in the conventional acid leaching process of molybdenite and other molybdenum-containing sulfide minerals can be solved, SO2 flue gas emission pollution is reduced, copper and molybdenum are synchronously separated, meanwhile, efficient oxidation of molybdenum concentrate under the wet process condition is achieved, and efficient enrichment of molybdenum in acid leaching residues is promoted. By the adoption of the preparation method, efficient oxidation and copper-molybdenum separation of the molybdenum concentrate can be achieved in the catalytic
