Abstract
When coal is combusted, such as in the process of generating electricity, fly ash is produced in abundant quantities. Methods and systems are provided for extracting materials, such as rare earth elements critical for national security or nuclear power generation, from fly ash. A method of processing fly ash includes installing a collection system in a fly ash pond. The method further includes applying water to the top surface of the fly ash pond, such that the water leaches through fly ash and into the collection system. The leached water is processed to remove materials, such as rare earth elements. Systems are also provided.
