| Summary: | Increasing environmental concerns over the use of cyanide for gold recovery has intensified the need to deeply understand gold thiosulfate leaching system. Therefore, experimental and modelling work for the kinetics and equilibrium adsorption of thiosulfate, polythionates, gold and copper onto strong based anion exchange resin have been conducted in this study, and the results are concisely discussed in the thesis. Experimental procedures, reaction mechanisms and novel dynamic models for the adsorption phenomena were also proposed. |
