以铜钼硫化矿浮选体系中的电化学理论为基础，研究了在硫化矿表面发生的5类典型的阳极氧化反应在处理斑岩铜矿过程中的浮选意义。研究结果表明：在抑硫混合浮选铜钼过程中关键是控制好第1、2类阳极反应，同时注意到第3类阳极反应；在混合精矿脱硫浮选中应主要控制第1、4类阳极氧化反应；在铜钼分离浮选中要求严格控制第4、5类阳极氧化反应。本文还介绍了针对额尔登特铜矿石的电化学控制浮选实验室研究和工业试验应用情况。

Based on the phenomenon of electrochemistry occurring in flotation process, five kinds of anode reactions on surface of sulfides are discussed separately in flotation processing of copper sulfides in this paper. It is noted that the anode reactions of oxidation of xanthate and formation of collector salts on copper sulfides are the key problem in copper and molybdenum bulk flotation while pyrite is depressed, the anode reactions of oxidation of xanthate and decomposition of collector salts are the main reactions in the separation of copper sulfides from bulk concentrate, etc. A commercial application of Electrochemical Control Flotation (ECCF) as a result of the research on the porphyry copper ore is introduced especially.
