摘要/Abstract

摘要： 应用线性电势扫描法研究硫化矿的纯矿电极与碳糊电极体系在氯化钠电解液中的电化学行为.结果表明,乙炔黑在硫化矿浸出过程中起到电催化作用,加入乙炔黑的碳糊电极较之纯矿电极,其发电浸出输出电流和电压均有一定程度的增加,同时活化能较传统浸出的低.

Abstract: The cyclic voltammetry curves of sulfide mineral electrodes or corresponding carbon paste electrodes in NaCl electrolytes have been obtained in this study. The experimental results indicate that acetylene black (revealed) the electro-catalytic propertyin the electrogenerative-leaching process of sulfide minerals. The output currentand potential of carbon paste electrodes were increased to some degrees while the activation energies were lower.
