ABSTRACT:
A gold recovery process is disclosed in which the gold content of ores, including carbonaceous ores or mixtures of carbonaceous and oxide ores, is extracted by a simultaneous chlorine leach and ion exchange resin adsorption procedure. The process eliminates or reduces the degree of oxygenation and cyanidation required to conduct a standard gold extraction process.
