  • Alkaline sulfide gold leaching kinetics ScienceDirect

    The alkaline sulfide leaching rate of gold was found to be largely temperature dependent, with greater leach rates occurring at higher temperatures. The activation energy of the 50 g L 1 sulfide and 25 g L 1 polysulfide system was 41.6 kJ mol 1, indicating that the dissolution of gold in this polysulfide/sulfide system is chemically controlled.
