Ion exchange resins are an attractive alternative to activated carbon in both column and resin-in-pulp processes for the recovery of gold from cyanide solution. Resins are widely used for this purpose in the Soviet Union apparently in preference to activated carbons. A wide range of resins are available and the high level of resin technology...
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.

Ion exchange is a common hydrometallurgical processes used, and is well suited for recovery of low to moderate concentration targets from complex liquors. During ion exchange, metal ions are adsorbed from the pregnant solution onto the ion exchange resin, and a product solution is created when the resin is desorbed.
