介绍了高铅铜型难处理金矿矿浆电解浸出机理的研究结果。金精矿在矿浆电解时，铅的浸出可通过化学溶解、化学氧化、阳极氧化三种途径；铅浸出的主要途径是靠化学溶解，矿粒与阳极接触而被氧化对浸出的贡献不大。

Leaching mechanism of refractory gold concentrate in slurry electrolysis process has been studied. Lead can be leached out through chemical dissolution, chemical oxidation and anodic oxidation. It has been proved that the main way of lead leaching is chemical dissolution and chemical oxidation of gold concentrate is little.
