The concentration of rare earth elements from coal fly ash

Recently, coal fly ash has become a potential candidate as secondary resource of rare earth elements (REE). In this investigation, we studied the recovery REE from commercial power plant. The specific aim was to assess technical feasibility recovering using conventional preconcentration methods, including gravity separation, magnetic and froth flotation. experimental results revealed that flotation achieved major gains in upgrading. However, during wet separation tests, bulk reported tailings. showed significant variations performance various beneficiation methods investigated. This study confirmed existing physical could be used recover prior hydrometallurgical pyrometallurgical processing, although some challenges persist.
