According to the characteristics and shortcomings of the traditional roasting process and the electro-oxidation process in the molybdenum metallurgical industry, the ultrasound electro-oxidation process was proposed to strengthen the oxidative decomposition or leaching of mo- lybdenum. Laboratory work was carried out in an electrochemical cell with 15 mm electrode spacing at 25°C under ultrasonic effect. The op- timum conditions were found through experiments. The electro-oxidation mechanism of molybdenite decomposition under ultrasonic was investigated. A model of electro-oxidation mechanism of molybdenum under ultrasonic was given.
