Extraction of impurities: REM and other metals, from phosphoric acid
Keywords:
acid retardation method, REE.
Abstract
A presentation demonstrates the process of extraction of rare earth elements from industrial
phosphoric acid using the method of « acid retardation». The dependences of dynamic sorption curves of
phosphoric acid and additives of REE are shown dependently on sorbent type and grain sizes, as well as flow
rates of solution under treatment. For avoiding sedimentation in column beds, the optimal composition of
regeneration solution is found
