Cyanide Release Characteristics of Solid Waste in Gold Smelting Process

To explore the relationship between total cyanide and easily liberatable in tailings its impact on environment, leaching release characteristics of a pond were studied using dynamic experiment, model was established. The results show that concentration is higher than cyanide. With increase time, more sensitive to intensity. first-order kinetic, second-order modified Elovich, double constant, parabolic diffusion equations used fit cumulative According kinetic release, addition equation, other four revealed good fitting for process, which shows released under simulated rainwater not simply via surface diffusion, but controlled by multiple factors.
