摘要

摘要:
离子浮选是一种回收溶液中金属离子的有效方法，通过向浮选体系中加入表面活化剂与目的离子在气-液界面上发生物理吸附或化学吸附，然后用浮选法得到分离，因其具有回收率高和环保等优点，在废水处理、湿法冶金和海水资源化利用等领域得到了广泛应用。文章详细总结了金属离子浮选的作用机理及影响因素，简要叙述了离子浮选在相关领域的研究进展及应用现状，分析了离子浮选应用的技术难题，指出了金属离子浮选的发展趋势。

Abstract:
Ion flotation is an effective method of recovery of metal ions from the solution. because it has the advantages of high recovery and environmental protection. By adding surfactant to the flotation system, physical adsorption and chemical adsorption on the liquid-gas interface occurs with the target ions. Then ions separation is obtained by flotation method. Because of its high recovery rate, environmental protection and other advantages, it has been widely used in the fields of wastewater treatment, hydrometallurgy, and water resource utilization. In this paper, the mechanism and influencing factors of metal ion flotation are summarized in detail. The research progress and application status of ion flotation in related fields are briefly described. The technical problems of ion flotation application are analyzed. The development trend of metal ion flotation is pointed out.
