EXTRACTION OF RARE EARTH ELEMENTS AND CARBON RICH SOLIDS FROM COAL FEEDSTOCK USING IONIC LIQUIDS

摘要

Rare earth elements and carbon rich solids are extracted from coal feedstock by combining a coal feedstock with an ionic liquid, forming a mixture. The mixture is heated and a co-solvent is added. Carbon rich solids and rare earth elements are removed from the solution. The ionic liquid and co-solvent may be reused.
