Abstract: As a typical rare metal, gallium is widely used in wireless communications, LED lighting, semiconductors and solar cells, and is an important strategic metal resource. In recent years, the communications industry has developed rapidly, and the demand for gallium has also increased. The development of technology for recovering gallium from various gallium-containing resources has attracted much attention. This article reviews the methods and technologies for recovering gallium from secondary resources such as aluminum, zinc smelting, fly ash and industrial waste containing gallium, and summarizes and prospects its application.
