Strategies For Optimisation of Gold Processing Plants
Effect of pH on Au Recovery in the Presence of 0.25% Stibnite (After Hedley & Tabachnick 1968) Extrapolating the above trend back to the ordinate axis we note that recovery is once again achieved at pH 8.9 but with the reservation that gold recovery will reduce somewhat, and cyanide consumption increase, as the free CN- ion is replaced by dissolved HCN at the lower pH.

0304-386X/85/$03.30 1985 Elsevier Science Publishers B.V. 152 reduced the time required to strip gold from carbon from 48--72 hours to 8--12 hours. About the same time, investigations at the Anglo American laboratories (Martin et al., 1976) showed that gold could also be readily eluted by pure organic solvents or their azeotropic mixtures after ...

The carbon in the reactor into which pregnant pulp is fed (referred to as the first reactor) becomes highly loaded with gold. Loaded carbon values on operating plants range from 300 to 20 000 grams of gold per ton of carbon, a concen-trating factor of about 1 000–1 500. A portion of the loaded carbon is periodically removed from the first ...

It adsorbs the gold-cyanide complexes from the solution, effectively concentrating the gold. Elution: After the carbon has adsorbed a significant amount of gold, it is removed from the adsorption tanks and subjected to elution. In elution, the carbon is treated with a hot, concentrated cyanide solution to strip the gold from the carbon.
