Investigation of Removing Iron from Fly Ash | Scientific.Net

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.

Recycling Fly Ash Turns a Lump of Coal into

Fly ash makes up more than half of coal waste, and 99% of it is filtered by power-plant exhaust stacks. But rather than divert that filtered ash to landfills, one solution gaining traction is ash recycling. The recycling process renders the ash not only safe for use but also viable as an ingredient in products such as concrete and wallboard, creating stronger materials than sources

Coal Fly Ash Ceramics: Preparation,

Coal ash is a byproduct of mineral coal combustion in thermal power plants. This residue is responsible for many environmental problems because it pollutes soil, water, and air. Thus, it is important to find ways to reuse it. In this study, coal fly ash, obtained from the Presidente Médici Thermal Power Plant, was utilized in the preparation of ceramic supports for the immobilization of the
