A Pollution Prevention and Economically Viable Technology for Separation of Rare Earth Elements (REEs) from Powder River Basin Coal Ashes (DE-FE0027069)

摘要

1. All the goals set for the project are achieved, especiallyrn1.1 The actual REEs concentrations (the highest one to date: ～35% in products the set goal (2%); and >10% or 10% is achievable.rn1.2 The tons of qualified coal ashes we found the set goal (15M tons)rn2. A new pathway for producing critical materials - REEs is opened by integrating the knowledge from multi fieldsrn2.1 With various desired characteristicsrn2.2 Without the limitation of location and time.
