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.
