摘 要: 综述金属离子对矿物浮选行为的影响及机理，总结和分析直接因素(金属离子种类、价态和浓度等)与间接因素(目的矿物类别、矿浆溶液化学条件(pH和电位)、浮选药剂等)作用下，金属离子对矿物浮选行为的影响规律。据此，探究特定矿浆溶液化学条件对金属离子活化(抑制)矿物浮选的内在原因，提出金属离子影响矿物浮选行为的直接和间接作用机理，为理解金属离子对矿物浮选行为的影响提供参考。

Abstract:The influence of metal ions on mineral flotation behavior and the underlying mechanisms were reviewed in this work. The relative direct factors (category, valence state and concentration of metal ions) and indirect factors (mineral of interest, solution pH and potential, and flotation reagent) were summarized and analyzed. Accordingly, the direct and indirect interaction mechanisms of the activation or depression effect of metal ions on mineral flotation were outlined, which improves better understanding of the role of metal ion in mineral flotation.

Key words: metal ion; activation; depression; flotation; mineral
