Abstract

Unloaded polyether-type resilient polyurethane foams are used for the sorption and recoveroy of gold from ammoniacal cyanide media. The sorption capacity for gold is about 5 mg g-1. Sorption with about 95% recovery is possible on successive 5-g and 2-g foam columns at flow rates of 10-20 ml min-1. A pumping foam column in a syringe is also satisfactory.
