A study has been conducted to understand how heavy metal ions affect the dissolution behaviour of gold in the ammoniacal thiosulphate system. The effect strongly depended on ion types and concentrations, and reagent concentrations. Zn had a slightly positive effect on gold dissolution at very low concentrations, and would retard it at high concentrations. Cd, Co, Cr and Ni retarded gold dissolution...
This study was carried out on a finely disseminated gold-bearing ore from Kaymaz, Turkey. The main objective was to determine the mechanism of reaction between thiourea and Fe 3+ in the thiourea leaching of gold. Thiourea consumption levels were also examined during the leaching operations for different leaching parameters, i.e., molar ratio of ferric sulfate/thiourea, pH, and temperature...
