The leaching of gold from amalgamated tailings using the wet chlorination method has been successfully carried out. In this study, the gold leaching process was undertaken with percent solids varying at 10%, 15%, 20%, and 25% by using 30% H2O2 as an oxidizer. Subsequent leaching with 25% of solids without using 30% H2O2 oxidizer. For other operating conditions, it was kept constant with an operating temperature of 60°C, sample weight of 100 grams, and particle size of 200 mesh. The results showed that the highest gold recovery was 58.68% at 25% of solid. Meanwhile, the lowest gold recovery was 10.94% at 10% of solid. The use of H2O2 has a significant effect on the value of gold recovery, i.e using H2O2 the gold recovery is 58.68% compared to without using H2O2 of 1.15%.
