Investigation on the Extraction of Aluminum and Iron from Fly Ash by Sodium Carbonate Fusion Method

Abstract:

In recent years, utilization of fly ash has gained much attention in public and industry, which will help reduce the environmental burden and enhance economic benefit. In the utilizations of fly ash, the most high value-added applications is extraction of metal elements from fly ash. In this paper, the aluminum and iron extraction was investigated by orthogonal experiments. The results show that the optimum extraction condition was reaction temperature 800 °C, reaction time 3 h, the mass ratio of fly ash to Na₂CO₃ was 1:1.5.
