| Abstract: | The transform regularity of gallium in process of extracting alumina from alumina-rich fly ash is studied.Setting up sampling point in the production process,the enrichment and distribution of gallium is detected and analyzed.The results show that 75％ gallium in the alumina-rich fly ash enters into aluminium hydroxide product,and in the carbon circulating mother liquor,the concentration of gallium is the highest,which reaches 46.0 mg/L. |

| Keywords: | alumina-rich fly ash sintering process gallium transform regularity |
