  • The process design of gold leaching and carbon-in-pulp

    2009-8-27 · Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide.Town Cape of University University of Cape Town,2020-12-8 · Figure 21 : Cyanide Concentrations in the Leach with Random Cyanide different sections of the plant and it is therefore important to distinguish which phase each component occurs in.

  • Gold CIL & CIP Gold Leaching Process Explained CCD

    2013-1-2 · Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for Gold Metallurgy & Leaching in Cyanicides,2016-7-14 · Cyanidation as applied to ordinary gold and silver ores is a relatively simple process. When cyanicides {cyanide-consuming elements) are encountered in small amounts in the treatment of such ores, the various schemes already discussed, such
