| 摘 要： | 采用双电池技术,对Ag+,Ce4+,La3+和Cu2+等金属离子及辐照作用在硫化矿发电浸出过程中的影响进行了初步的研究.研究结果表明,由于矿物本体或矿物与浸出液的界面性质发生变化,使得发电浸出过程中电极极化程度减弱,输出电流、电压和相应的浸出速率提高.

| Abstract: | The dual cell technique was preliminarily used to study the influence of some metal ions(Ag~+,Ce~(4+),La~(3+) and Cu~(2+)) and radiation on the electro generative leaching of sulfide minerals electrode. The results show that there exists the transformation in structure of minerals and interfacial character between minerals and solution, which results in an increase in the current and potential output as well as the leaching efficiency simultaneously. |
