本文针对磁场在湿法冶金中的作用,利用化学分析测得磁场和不同温度的氯化铜浸出硫化砷渣的浸出速度,对每组数据是五次的平均值。利用阿累尼乌斯方程研究了浸出过程的动力学。实验结果证实浸出过程是化学反应控制,求得浸出反应的活化能由未经磁场作用的67.14kJ/mol降至磁场作用下的50.72kJ/mol,从而提高了浸出率和浸出速度。说明磁场作用于溶液中的极性分子,改变了一些分子的结构和能级状态,对一定的化学反应起到“激发活化”作用。指出了永磁磁场在湿法冶金过程中的应用前景。
In this paper, the role of magnetic field in hydrometallurgy, the use of chemical analysis of the measured magnetic field and different temperatures of copper chloride leaching sulfide arsenic leaching rate, for each set of data is the average of five times. The kinetics of the leaching process was studied using the Arrhenius equation. The experimental results show that the leaching process is controlled by chemical reaction and the activation energy of the leaching reaction is decreased from 67.14 kJ / mol without magnetic field to 50.72 kJ / mol with the magnetic field, thus improving the leaching rate and leaching rate. It shows that the magnetic field acts on the polar molecules in solution and changes the structure and energy level of some molecules and plays a role of “activation and activation” to a certain chemical reaction. The application prospect of permanent magnetic field in hydrometallurgy is pointed out.
