| description | The present article is focused on extraction alumina from high alumina fly ash using an improved hydro-chemical method with high-efficiency alkali circulation and mild reaction conditions. The alumina leaching behavior and corresponding reaction mechanism of the process were systematically investigated. The results revealed that the alumina extraction efficiency reached 50.7% in the low alkali process with alkali concentration of C(Na

O) = 230 g/L, and the total alumina extraction ratio reached 92.4% in the high alkali process with alkali concentration of C(Na
