Extraction of Aluminum from Coal Fly Ash by Acid Leaching

The conditions of roasting activation of coal fly ash with KF as assistant and extraction of aluminum by acid leaching were studied. The effects of conditions of roasting activation and acid leaching on the leaching rate of aluminum from coal fly ash were investigated, and the leaching kinetics studied. The results show that the optimal conditions of roasting activations were obtained as
