a theoretical study of the carbon in pulp process for gold,may 04, 2001 1. introduction. the carbon in pulp process for gold recovery involves treatment with cyanide under aerobic conditions at high ph, to give the au(cn) 2 ion, which is then recovered by adsorption on carbon, followed by elution of the au(cn) 2 in caustic solution and electrowinning of the gold. in this study, the stability of models of the carbongold complexes are studied by hartree.a theoretical study of the carbon in pulp process for gold,calculations the carbon in pulp process for gold recovery species to be studied were set up with the program involves treatment with cyanide under aerobic condi- hyperchem 2 and calculations were done with tions at high ph, to give the au cn 2 2 ion, which is gaussian 94 3, running on a dec alpha worksta- then recovered by adsorption on carbon, followed by tion, using the lanl2dz effective core.
a process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.,carbon in pulp plant,jul 26, 2017 carbon in pulp plant. sslurry at a rate of approximately 3.785 cu. m. per minute (1,000 gpm) is placed in contact with activated carbon. a simplified flow-sheet of the cip plant is shown in figure 2. for years it has been known of the affinity of activated carbon to adsorb preferentially the gold and silver in cyanide complex form.

this paper presents water the footprint assessment (wfa) of carbon in pulp (cip) gold processing. the main objectives of the study are determining grey and blue water footprints and identifying the hotspots of the process. results revealed that the total blue water footprint, including the extraction and processing of the gold, was found to be 452.40 m3/kg au, and the grey wf to be 2300.69 m3,carboninleach jacobi group,the carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation in which the leach tanks are fitted with carbon retention screens and the carbon-in-pulp tanks are eliminated. the activated carbon is added in leach, with gold adsorption occurring nearly simultaneously with gold dissolution by the cyanide
carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. in the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously.,gold cil cip gold leaching process explained,jan 02, 2013 the carbon-in-pulp process is used to treat low grade gold and/or silver ores. the ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. this is done to produce a feed suitably sized so that subsequent leaching is rapid.
