Extraction of Aluminium and Iron using Mineral acids from Talcher Thermal Power Station Fly Ash

Niva Nayak

Abstract :

Now a days the industries of developing nations are generating a huge amount of fly ash with more and more generation of power. Fly ash is a harmful pollutant and is linked to various environmental problems for which its proper disposal and utilization is highly needed. As fly ash is rich in various inorganic constituents it can be considered as a waste of recoverable resources for metal extraction. In the present study attempts have been made to study the leaching behaviour of TTPS fly ash using mineral acids such as HCl, HNO₃,o–H₃PO₄ and H₂SO₄ .The study found  HCl and HNO₃ suitable leachant for iron extraction compared to other acids. In a similar way o–H₃PO₄ and H₂SO₄ are found suitable leaching agent for Aluminium extraction. The extraction behavior is further supported by the characterization of post leached ash residues by XRD,Particle size and SEM.
