In this study, the leaching rate of molybdenite concentrate was evaluated in sulfuric medium, and the influence of the diverse oxidants including hydrogen peroxide, manganese oxide, copper sulfate on the leaching rate was studied. Also, the effect of the addition of the ethylene glycol to the hydrogen peroxide was studied and results showed that with the addition of ethylene glycol, the leaching rate is increased 55% from 41% up to 80.3%. The optimum condition is achieved as 0.7 M of H₂SO₄, 4.4 M of H₂O₂, and 3.5 M of EG at 30 °C within 4 h of leaching time and 500 rpm. Also, inserting the oxygen with the pressure of 6 bar to the leaching autoclave, the leaching rate is increased more up to 86.4%. Finally, the leaching process was studied kinetically and the determined mode of controlling factor was specified based on the activation energy which equals 46.252 kJ/mole indicating the chemical reaction mode.

本研究对辉钼精矿在硫酸介质中的浸出率进行了评价，研究了过氧化氢、氧化锰、硫酸铜等多种氧化剂对浸出率的影响。此外，研究了乙二醇对过氧化氢的影响，结果表明，加入乙二醇后，浸出率从41%提高到80.3%，提高了55%。最佳条件为 0.7 M H ₂ SO ₄、4.4 M H ₂ O ₂, 和 3.5 M 的 EG 在 30 °C 的浸出时间和 500 rpm 的 4 小时内。此外，在浸出高压釜中通入 6 bar 压力的氧气，浸出率进一步提高到 86.4%。最后，对浸出过程进行了动力学研究，并根据化学反应模式的活化能46.252 kJ/mole确定了控制因素的确定模式。
