| Abstract: | From the early stage of the fly ash extract gallium pretreatment smelting alkali and acid leaching method carried on the experiment contrast,the basic flux and oxidation alkaline fluxing agent were determined. The temperature was 700 －750 ℃ and the leaching rate was 98. 8%. The new,useful and practical method of extracting gallium from coal fly ash was obtained. |
