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 ...
Synthesis of hydrometallurgical processes for valorization of secondary raw materials using ant colony optimization and key performance indicators
(Elsevier, 2015-02-16)
An algorithm-based method for synthesis of hydrometallurgical processes using limited amounts of experimental data is presented. The method enables simultaneous selection and sequencing of unit operations and optimization ...
