Schematic diagram of a carbon-in-pulp or carbon-in-leach plant with three tanks, showing the interstate screens (IS), the screen at the exit of the first tank (S), and the carbon transfer pumps (P).

Still further features of the invention provide for loaded carbon removed from the lowermost stage to be eluted, initially if necessary with acid to remove adsorbed calcium carbonate followed by elution of gold using any acceptable elution process such as the Zadra or Aarl procedures; for the barren overflow pulp to be treated in suitable equipment, for …

The gold CIP process includes seven operation stages: preparation of leaching pulp, cyanide leaching, carbon adsorption, gold-loaded carbon desorption, electrolysis to …

Diesel or kerosene can be added to the pulp [11] to blind the "natural carbon," but it also fouls the activated carbon adsorbent. Resins are not fouled to the same extent as activated carbon by these additives and can be successfully used in the presence of some organic blinding agents. ... An Innovative Approach to Extracting Gold from ...

A steady-state simulator for CIP/CIL circuits has been developed. The simulator is based on a model of a single CIL tank. This model combines descriptions of the kinetics of leaching, the kinetics of adsorption, and the residence time behaviour of the pulp solids, leach liquor and carbon. This work was part of a co-operative research project …

Gold carbon in leach(CIL) is a gold extraction process in which the two operations of cyanidation leaching and activated carbon adsorption of gold are partially or completely carried out at the same time. In view of the high cyanidation leaching rate at the initial stage of leaching and the gradual reduction of cyanidation leaching rate, most of the carbon in …
