Ultrasonic Electro-oxidation Process of Molybdenite Concentrate

The oxidation of MoS2 concentrate in NaC1 solution electrolysis environment and the impact of ultrasonic field on the leaching process of Mo were investigated.The decomposition process of MoS2 can be accelerated by ultrasonic field.When there are iron ions,anode potential is decreased about 0.7V than that without iron ions.iron ions in the solution play an electronic transmission role by directly ioining the electrode reaction of anode and oxidation lcaching process.The results indicate that the leaching rate of Mo Can achieve 99.5% with ultrasoinc field exertion working 4 min in every 5 min under the conditions that the liquid-solid ratio is 20,mixing rate 500 r/min,iron ion concentration 6%,leaching temperature 40℃,pH(initialization)1,and leaching time 4 h,respectively.
