Funded Activity Summary

Modified activated carbons for recovery of gold from thiosulphate solutions. Thiosulphate is currently being considered by various international mining companies as an environmentally friendly alternative to cyanide for gold extraction. Although little is available in the open literature, most confidential research on recovery from thiosulphate leach slurries has focused on ion-exchange technology. Activated carbon as a more practical sorbent has been ignored completely owing to the general perception that it has a very low affinity for gold thiosulphate. On the basis of promising preliminary work, the aim of this project is to develop physically and chemically modified activated carbons with a high affinity for the sterically large gold thiosulphate complex. This project will aim to prove the hypothesis that the graphitic edges of an active carbon should be maximised and the organic active sites minimised for optimal adsorption.
