Investigation of Removing Iron from Fly Ash

Abstract:

Fly ash, as an environmental pollutant, is generated in the process of coal combustion for energy conversion. It has been widely used in so many applications, such as, preparation of zeolite, extracting alumina, and so on. Iron composition has some side-effect on the purity and whiteness of the products prepared form fly ash. In this paper, removal of unburned carbon and iron composition was investigated. The results show that the carbon can be removed completely from fly ash after calcination under 800°C for 2h. Acid leaching was used to remove iron from the fly ash after decarburization. The optimum processing parameter is, hydrochloric acid concentration 5mol·L^-1, reaction temperature 80°C and reaction time 2h.
