    The results were used to determine the controlling step of the cementation at low cyanide concentration and to interpret the influence of the variables on this process. These values do not adequately describe the global cementation reaction because gold reduction in low cyanide concentration solutions is greatly influenced by a strong contribution from adsorptive processes.
