Partitioning of Rare Earth Elements (REEs) from Coal to Coal Fly Ash in Different Thermal Power Stations (TPSs) of India

Rare earth elements (REEs) have been a topic of profound interest for several decades especially in the present age electronic and digital revolution. India has world’s richest beach sands with REEs, yet it imports some strategic REEs to fulfil its demand. It’s high time explore alternative sources meet demand coal ash from Thermal Power Stations (TPS) can be very good resource. In study, fly (CFA) seven Indian TPSs evaluated estimation variations minerals compositions. Mineralogy samples is estimated using X-Ray diffraction (XRD) technique. Coal mostly consist quartz kaolinite however phase transformations occurred due temperature treatment during combustion. CFA contains mullite. determined by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) considerable occurrence any specific REE not observed. Among studied TPSs, Pr highest concentration among ash, reaching up 63 ppm. The Outlook Coefficient (Cout) range 0.3–4.5 0.1–1.2 respectively. this research paper, Enrichment (?e) introduced see enrichment respect mother graph ?e vs glassy plotted observe partitioning REEs.
