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 ...
Ion exchange recovery of rhenium from industrially relevant sulfate solutions: single column separations and modeling
In this study, phenomena behind recovery of Re by weak anion exchangers from sulfate solutions containing Mo and As as impurities were investigated. All the metals exist as different kinds of oxyanions or, at some conditions, ...
Ion exchange recovery of silver from concentrated base metal-chloride solutions
Ion exchange has not been extensively studied nor industrially used for recovering small amounts of silver from concentrated base metal-chloride solutions. A novel multistep process utilizing a weak anion exchanger with ...
