摘要：
Galena is a major lead-bearing mineral with semiconductor properties, and its flotation process involves the electrochemical reaction. During the electrochemical process, there will exist electron transfer, galena surface oxidation, pH changing, potential changing, reagent molecular oxidation and interaction with galena surface. Above factors affecting electrochemical behavior were comprehensively analyzed in this article. Meanwhile, the focus and direction of current research were discussed, for instant, electrochemical research should focus on the combination of theory and application, and according to the electrochemical behavior of galena flotation, by adjusting and controlling parameters such as pulp potential, dissolved oxygen and pulp pH to improve the flotation pulp system and optimize the flotation index. In addition, it is necessary to improve the ecological environment of the mine and minimize the dissolution of toxic and harmful elements such as Ge, Hg, and Tl. © 2022, China Science Publishing & Media Ltd.
