“…The contents of Ge, In, and Ga in different resources are shown in Table 4. Hydrothermal alkaline leaching was used to leach Bayer red mud to achieve Ga/Fe separation and Ga enrichment [44]. Under the optimal conditions, the leaching rate of Ga was 91.4%, and the Ga 2 O 3 concentration in the leaching solution reached 73.44 mg/L.…”

Gallium (Ga), indium (In), and germanium (Ge) play an important role in the modern high-tech material field. Due to their low content and scattered distribution in the crust, and the increasing demand for these metals in recent years, their supply risks have sharply increased. Therefore, the recycling of these metals is of great significance. In this work, a systematic review was performed using the Web of Science, Scopus, MDPI, Elsevier, and Springer Link databases. The combined terms used for the search were Ga/In/Ge, extraction, separation, and recycling. After a careful evaluation of the titles, abstracts, and full texts, a total of 106 articles were included. This paper briefly describes the resource features of Ga, In, and Ge. After that, the chemical principles, technical parameters, and metal recovery in various extraction and separation methods from monometallic and polymetallic resources are systematically reviewed. Leaching followed by solvent extraction or ion exchange is the main process for Ga, In, and Ge recovery. Although many attempts have been made to separate multiple metals from leaching solutions, highly selective solvents and resins are still the research priority. This review can provide theoretical and technical guidance for the separation of Ga, In, and Ge from various resources.

“…The experimental results indicated that this process was a facile and effective method to recover Ga from RM. Besides, Xue et al (2019) found that gallium exists in RM in the form of Ga(OH) 3 , but Fe(OH) 3 wrapped on its surface hinders contact between Ga(OH) 3 and leaching agents. Thus, hydrothermal alkaline leaching method was used to transfer Fe(OH) 3 into Fe 2 O 3 with a small specific area, which makes Ga(OH) 3 to interact with NaOH.…”

Red mud (RM) is a solid waste generated during the process of alumina production. RM has already posed a serious environmental threat with the development of the alumina refining industry. The comprehensive utilization of RM has attracted much attention due to its large-scale generation and harmful nature. This paper introduces the characteristics and state of RM and summarizes the relevant research on the comprehensive utilization of RM. The results show that comprehensive utilization of RM is mainly focused on the preparation of building materials, the extraction of valuable metals, catalyst synthesis and environmental protection. Besides, the article discusses the existing problems while utilizing RM. Prospects and suggestions for different utilization methods of RM are proposed.

“…However, Ga usually occurs as a trace element in a range of minerals (e.g., bauxite and Zn ores), and therefore, no mines endowed of Ga as main commodities have been discovered so far (Shao et al, 2018;Ji et al, 2020;Zhan et al, 2020). As a consequence, the bulk of the global Ga derived from bauxite (e.g., karst-type bauxites) and Zn ores (e.g., Mississippi Valley Type) is exploited as a by-product from Al and Zn production (Lu et al, 2017;Xue et al, 2019;U.S. Geological Survey, 2021).…”

Gallium (Ga) and aluminum (Al) belong to group ⅢA elements in the periodic table.They show a coupled geochemical behavior in most natural systems, and are considered as "geochemical partners". However, compared with the principal oxyhydroxides of Al in nature, gibbsite (Al(OH) 3 ), boehmite (γ-AlOOH), and diaspore (α-AlOOH), only the analogs söhngeite (Ga(OH) 3 ) and tsumgallite (α-GaOOH) were reported. In this work, boehmite-type GaOOH (γ-GaOOH), a new polymorph of GaOOH, was synthesized for the first time using boehmite (γ-AlOOH) as a template. The synthesized γ-GaOOH was characterized by a series of techniques including X-ray diffraction (XRD), high angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) and selected area electron diffraction (SAED). Furthermore, a model based on the boehmite structure was successfully applied to define the γ-GaOOH structure by the Rietveld method. Results from sample characterization and structural refinement support the successful synthesis of boehmite-type GaOOH, and thus it is referred to as γ-GaOOH. The synthesis of γ-GaOOH in laboratory is valuable to understanding the Ga geochemistry and its enrichment process in Ga-rich boehmite in coal and bauxite.
