Recovery of Gallium and Vanadium from Coal Fly Ash - 論

A process has been developed to recover gallium and vanadium from coal fly ash in which they exist at very low concentration in a mixture of high concentration of less desirable species. Aqueous solution containing 2.8 mg/l gallium and 35 mg/l vanadium was obtained by leaching with 1.5 mol/l sulfuric acid. These metals were then concentrated by use of a chelating resin
