摘要: 考查了不同磨矿介质下,黄铜矿新鲜矿浆与放置24 h后矿浆pH值与矿浆电位的关系,通过测定矿浆中铁离子含量及溶氧量,分析了pH=4.67时黄铜矿磨矿体系矿浆电位变化的原因,并通过测定铁介质和黄铜矿间的迦伐尼电流,考查了黄铜矿和铁介质在不同pH条件下原电池相互作用的强弱。

Abstract: The relationship of pulp potential and its value of the fresh pulp and the pulp after 24 h of chalcopyrite with different grinding media are studied. Through determining the concentration of Fe2+ and dissolved oxygen (DO), the variety factors of pulp potential in chalcopyrite grinding at pH 4.67 is explained. The electrochemical interaction between iron and chalcopyrite under different pH is observed by galvanic current measurement.

Key words: Grinding media, Chalcopyrite, Pulp potential, Galvanic current
