2022, Separation and Purification TechnologyCitation Excerpt :However, Ga distribution in nature is relatively sparse; hence Ga is not the primary mineral in ore. Ga is generally recovered as a by-product of bauxite extraction via the Bayer process [5,6]. Thus, the cost of mining and producing Ga is costly [7].
Kinetic study of gallium electrochemical reduction in alkaline solution
2013, HydrometallurgyCitation Excerpt :For this reason there is a need for substantial increase of its output (Naumov and Plekhanov, 2011). Currently, the main source of gallium is aluminum raw materials processed by the aluminum oxide plants, which simultaneously extract gallium (Chou et al., 2008; Dovbysh et al., 1981; Gupta et al., 2007; Ibragimov and Budon, 2010; Ivanova, 1973; Kekesi, 2007; Korovin et al., 2003; Ma et al., 2011; Moskalyk, 2003; Puvvada et al., 1996; Wu et al., 2007; Xu et al., 2007; Zelikman et al., 1980; Zhao et al., 2012). Metal gallium is extracted from alkaline solutions in alumina production using electrochemical methods of recovery of its ions.
Recovery of gallium from Bayer liquor: A review
2012, HydrometallurgyCitation Excerpt :However, the final recoveries using ultrasound were found to be not more than 50% for real liquors. Another method for increasing the reaction rate is based on deliberate creation of a “water-in-oil” microemulsion in the organic phase (Dantas et al., 2002; Mihaylov and Distin, 1992; Puvvada, 1999; Puvvada et al., 1996). Fourre and Bauer (1983) have shown that a microemulsion was produced by the addition of a long chain alcohol such as butanol and the sodium salt of a long chain carboxylic acid such as octanoate to the organic phase containing Kelex 100.
