Two methods for extracting gallium from fly ash |
| abstract |
A method for extracting gallium from circulating fluidized bed fly ash from coal combustion, comprising the steps of: a) grinding the fly ash to a particle size which passes through a sieve with the sieve opening size of 149 microns (size of 100 mesh or smaller), removing iron by a wet magnetic deposition such that the iron oxide content in the fly ash to 1.0 wt % or less, then adding hydrochloric acid to the de-icing fly ash for an acid washout reaction and subjecting the reaction product to solid-liquid separation to yield a hydrochloric acid eluate having a pH in the Range 1 to 3; b) adsorbing gallium in the hydrochloric acid eluate by carrying it through column loading with a macroporous cationic resin; eluting the column with water or hydrochloric acid as an eluting agent when the adsorption reaches saturation to contain a gallium-containing eluate; c) masking iron ions in the gallium-containing eluate with a masking agent, followed by passing the masked eluate through the column loading with a macroporous cationic resin; eluting the column with water or hydrochloric acid as an eluting agent when the adsorption reaches saturation to obtain a second eluate; and ... |
