AbstractResearch at ICM on gold leaching and recovery related to thiosulfate system is briefed. Ammonia was found to promote the thiosulfate leaching of gold by preferential adsorption on the gold surface and dissolution of gold as an auroammine intermediate which then converts into thiosulfate complex. This will prevent sulfur species from adsorption on gold, resulting to form sulfur and sulfide passivation coating on its surface. Thiosulfate needed for gold leaching can be produced at the plant site by PTC disporportionation of elemental sulfur to mixed polysulphide and thiosulfate, followed by oxidation of the fresh polysulphide to thiosulfate with aeration. Solvent extraction of gold in thiosulfate solutions with neutral phosphorus esters, amines and their mixtures was also investigated.
