在锌电积过程中,电流效率是一项重要的经济技术指标,直接影响着湿法炼锌的生产成本。因此,有必要对影响锌电积电流效率的因素进行研究。在查阅国内外大量文献的基础上,综述了阳极材料、电积液中杂质离子、添加剂等因素对锌电积电流效率的影响,并对未来如何更好提高电流效率的研究方向进行了展望。
In the process of zinc electro-deposit, the current efficiency is an important economic and technical norm, which directly influences the production costs of zinc haydrometallurgy. So, it is necessary to research the influence factors of current efficiency of zinc electro-deposit. Based on great amount of domestic and broad literature, the effect of anode material, the impurity ions in electrolyte, addition agent and the other factors on current efficiency of zinc electre-deposit is summarized, and the future research direction that how to improve the current efficiency better was viewed.
