摘要：
The process of extracting aluminum with sulfuric acid from high-alumina fly ash activated by roasting with Na2CO3 and NaOH as raw materials ware studied. The results revealed that the aluminum in fly ash activated by sodium carbonate reached 93.2% under the optimum conditions (30% H2SO4, 90 degrees C, 120 min, and liquid-to-solid ratio was 5:1). Simultaneously, the leaching rate of aluminum in fly ash activated by sodium hydroxide reached 92%. The study of kinetics suggested that the leaching process with sulfuric acid was controlled through chemical reactions; it conformed to the kinetic equation: 1 - (1 - X) 1/3 = 22.924 exp[- 25174/(RT)]t.Graphical abstractExtracting aluminum with sulfuric acid from high-alumina fly ash activated by roasting with Na2CO3 and NaOH as raw materials.
