摘　　要：镓作为典型稀散金属被广泛应用于无线通讯、LED照明、半导体及太阳能电池等领域,是重要的战略金属资源。随着新能源、电子通讯、航空航天等高科技领域的快速发展,镓金属的需求量和用途也在不断增加。但是,镓在自然界中几乎不存在具有工业开采价值的独立矿床,其主要从铝、锌等金属生产过程中作为副产物所回收。因此,镓的产量受到了极大的限制,这迫使人们寻找新的含镓资源和更加高效回收镓的方法。本文综述了从拜耳法循环母液、炼锌渣、粉煤灰、电子废料等含镓工业二次资源中回收镓的方法和技术,并对其应用性进行了总结与展望。Gallium,a typical rare and dispersed metal,is widely used in wireless communications,LED lighting,semiconductors,and 9solar cells,making it a critical strategic metal resource.With the rapid development of high-tech fields such as new energy,electronic communications,and aerospace,the demand and applications for gallium metal are continuously increasing.However,gallium rarely occurs exists as independent ore deposits of industrial mining value in nature and is primarily recovered as a byproduct from the production of metals like aluminum and zinc.Therefore,gallium production is greatly limited,driving the search for new gallium-containing resources and more efficient recovery methods.This paper reviews the methods and technologies for recovering gallium from gallium-containing industrial secondary resources,such as Bayer process spent liquor,zinc smelting slag,fly ash,and electronic waste,and summarizes and prospects their practical applicability.
