Alkali extraction is an alternative to acid leaching for removing heavy metals from fly ash. The process can be performed using NaOH, NH 3 or Na 2 CO 3 solutions. Similar to acid extraction, the concentration of the alkaline leachate as well as the leachate type play a vital role in the metal removal efficiency of the process.
