Recovering rare earth elements from phosphogypsum using a resin-in-leach process: Selection of resin, leaching agent, and eluent
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
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 ...
