摘　　要：采用次氯酸钠作浸取剂研究了最佳的浸取条件,并做了浸出反应热力学和动力学分析.实验结果表明,浸取低品位钼矿的最佳工艺参数:液固比L∶S为17∶1,浸取温度为30℃,浸取时间为1h,浸取率为83.40%.浸出反应的△G0值为负值,从热力学角度看,次氯酸钠体系理论上能够对低品位钼矿等进行氧化分解,动力学结果表明:浸出反应符合Arrhenius经验式,反应活化能Ea=13.8 kJ/mol,该浸取反应可以进行.该浸取反应可以进行.The low-grade molybdenum is leached by sodium hypochlorite and then the optimal condition is determined.The thermodynamic and kinetics analysis on the low-grade molybdenite is also studied.Results show that： the optimal technological parameters of leach are： the ratio of liquor to solid is 17：1,leaching temperature is 30℃,leaching time is 1h,leaching ratio 83.40% The values of △G0 were negative and low-grademolybdenite could be leached by sodium hypochlorite theoretically.Leaching reaction in line with empirical Arrhenius,Ea =13.8kJ/mol,Leaching reaction can be complete.
