Product Details

Gold extraction resin is a high purity, premium grade, weakly basic macroporous anion exchange resin that is highly resistant to osmotic and thermal shock. It is primarily designed for effective recovery of aurocyanide complexes obtained from the alkaline cyanide processing of gold ores and offers a superior selectivity for gold against the basic metals exiting a pregnant solution. Gold extraction resin is supplied with a selected particle size required by Resin-in-Pulp gold recovery circuits.
