Recovering rare earth elements from phosphogypsum using a resin-in-leach process: Selection of resin, leaching agent, and eluent
(Elsevier, 2019-08-10)
Phosphogypsum (PG) is an attractive secondary raw material for rare earth elements (REEs) because it is abundant and contains significant amounts of REEs. Herein, the resin-in-leach (RIL) process for REE recovery from PG ...
Ion exchange purification of a silver nitrate electrolyte
(Elsevier, 2018-12-14)
A novel ion exchange process was studied to remove high concentration of Cu impurity from AgNO3 electrolyte was studied. A suitable ion exchange resin was screened using laboratory scale experiments with a synthetic nitrate ...
Recovery of rare earth elements from phosphogypsum waste in resin-in-leach process by eluting with biodegradable complexing agents
(Elsevier, 2021-02-02)
Phosphogypsum waste is a potential, secondary rare earth element (REE) source that is available in very large volumes. Extraction and purification of REE from this complex waste was studied using resin-in-leach (RIL) ...
