Basic Study on the Synergistic Extraction of V and Ga from Bayer Mother Liquor of Alumina Production
The synergistic extraction law of vanadium and gallium from Bayer mother liquor by OH− type LSC-600S resin was investigated in this paper. More than 72.21% of vanadium and 74.46% of gallium were adsorbed from Bayer mother liquor, when the conditions were resin of 4 g/L, adsorption time of 100 min, temperature of 70 °C, and stirring rate of 500 r/min. Thermodynamic calculations show that the extraction of vanadium and gallium by the resin proceeds spontaneously, and that an increase in temperature favors the extraction of vanadium and gallium. Theoretical research results showed that, the kinetics of adsorption process followed the pseudo-second-order reaction, and the adsorption isotherm followed the Freundlich isotherm model. The infrared spectrum analysis results showed that, gallium ions in solution interacted with the C=NOH in the resin, and vanadium ions interacted with the C=NOH and C–NH2. The synergistic extraction of vanadium and gallium does not reduce the adsorption capacity of the resin for gallium, but also effectively recovers vanadium. It provides a new method for the recovery of vanadium resources from Bayer mother liquor.
期刊介绍：
Journal of Sustainable Metallurgy is dedicated to presenting metallurgical processes and related research aimed at improving the sustainability of metal-producing industries, with a particular emphasis on materials recovery, reuse, and recycling. Its editorial scope encompasses new techniques, as well as optimization of existing processes, including utilization, treatment, and management of metallurgically generated residues. Articles on non-technical barriers and drivers that can affect sustainability will also be considered.
