摘要

摘要:
典型金属离子对闪锌矿浮选行为具有显著影响。总结了闪锌矿浮选矿浆体系中金属离子的来源，综述了Cu²⁺、Pb²⁺、Fe²⁺、Fe³⁺、Ca²⁺、Mg²⁺、Zn²⁺等金属离子对闪锌矿浮选行为的影响及其作用机制。根据金属离子本身的性质和浮选环境的不同，其作用效果和作用机制也有不同，分析表明金属离子是通过取代、吸附和覆盖的方式对闪锌矿可浮性产生影响。展望了金属离子在闪锌矿浮选中的应用前景，并提出了闪锌矿与金属离子作用机制的研究方向。

Abstract:
Typical metal ions have a significant effect on the flotation behavior of sphalerite. The sources of metal ions in flotation pulp system are summarized. The influence of metal ions such as copper, lead, calcium, magnesium, zinc, ferric and ferrous on the flotation behavior of sphalerite and its interaction mechanism are reviewed. According to the differences between metal ionic property and the flotation environment, the effect and functionary mechanism of metal ion are also different. The analysis shows that metal ions affect the floatability of sphalerite by substitution, adsorption and covering. The application prospect of metal ions in sphalerite flotation is prospected, and the research direction of interaction mechanism between sphalerite and metal ions is pointed out.
