Nicol, M.J., Fleming, C.A. and Cromberge, G. (1984) The absorption of gold cyanide onto activated carbon. I. The kinetics of absorption from pulps. Journal of the South African Institute of Mining and Metallurgy, 84 (2). pp. 50-54.
An account is given of the development of a relatively simple model that describes the kinetics of the absorption of gold cyanide on activated carbon. The model is based on the treatment of the carbon-solution interface as a homogeneous boundary across which gold is transported at a rate determined by the rate of mass transport to and from the interface. Rate equations derived from this model describe the results of various kinetic experiments under continuous or batch conditions in the laboratory and on operating pilot and full-scale plants.
