How Metal Impurities Affect Gold Adsorption on

2017-11-18  The effect of the cyanide complex impurities on carbon adsorption of gold was determined by adding sodium gold cyanide to the synthetic feed solution, producing a gold concentration of 150 ppm. This concentration is significantly higher than metal concentrations normally encountered in most gold

Rate of adsorption of gold cyanide on activated

The rate of adsorption of gold cyanide on activated charcoal was examined as a function of charcoal concentration and size, temperature, initial gold concentration, pH, and initial concentration of gold on the charcoal. Rate was found to be proportional to temperature, concentration of charcoal and initial gold concentration on charcoal, and to the inverse of charcoal particle size squared.
