Value in Waste: Fly Ash Reuse and Recovery Opportunities

One new study has taken alumina recovery research a step forward with some promising results; by combining a CaCl2 calcination step with H2SO4 leaching, researchers were able to obtain greater than a 95% recovery of alumina from the fly ash. In comparison, the study found direct acid leaching could only recover about 2 4.75% alumina.
