The present paper gave a comprehensive description of the recovery of gallium from production of alumina from high-alumina coal fly ash with predesilication and lime-soda sinter combination process. The low concentration of gallium in the spent liquor, along with the high concentration of aluminum, prompted the use of chelating ion exchangers as an alternative separation process. Gallium extraction studies were carried out using chelating ion exchangers. The experimental data were simulated and analyzed by Boltzmann distribution function. The paper also dealt with the pitting corrosion of carbon steel as well as corrosion resistance of the glass flake mortar. © 2016, Science Press. All right reserved.
