This report presents information on the state-of-the-art of metals recovery technologies to assist in identifying waste-management options for metalbearing sludges and wastewaters that may be regulated under the Resource Conservation and Recovery Act (RCRA). Only a few of the technologies addressed In this report (e.g., electrowinnlng, high-temperature metals recovery (HTMR]) are directly appli...

The extraction of Cu from mixed-metal acidic solutions by the thiourea-functionalized resin Puromet MTS9140 was studied. Despite being originally manufactured for precious metal recovery, a high selectivity towards observed over other first-row transition metals (>90% removal), highlighting potential this in base recovery circuits. Resin behaviour characterised batch-mode under range pH and ...

A simple ion imprinted amino-functionalized sorbent was synthesized by coupling activated carbon with iminodiacetic acid, a functional compound for metal chelating, through cyanoric chloride spacer. The resulting sorbent has been characterized using Fourier transform infrared spectroscopy (FT-IR), elemental analysis, thermogravimetric analysis (TGA) and evaluated for the preconcentration and de...
