  • Description:
    An investigation undertaken by the Bureau of Mines examined the recovery of gold by chlorination of refractory carbonaceous and sulfidic ores. Comparisons were made between various treatment methods in which a pulped ore is contacted with chlorine gas and activated carbon is added to the pulp for a carbon-in-chlorine leach (cicl). It was found that the organic carbon deactivating environment of cicl lowers, but does not eliminate, the adsorption of gold on activated carbon. The objective of this research was to demonstrate the basic feasbility of cicl technology. In this environment a refractory ore alteration, gold extraction, and recovery on activated carbon occurs. With highly carbonaceous ores, cicl achieved a higher recovery than with primarily sulfidic refractory ores. Basic cyanide amenability testing of two carbonaceous ores achieved only 5.5- and 46-pct recoveries, respectively. With cicl treatment, recoveries on carbon were 90 and 92 pct, respectively.
