Gold recovery from guanidine resins
This article describes some studies of dicyanoaurate anion elution from vinylbenzyl chloride resins containing guanidine ligands. The elution of gold (I) cyanide anions from loaded guanidine resin (resin with guanidine ligands) using sodium hydroxide eluent and modified caustic eluent: mixture of sodium hydroxide and sodium benzoate were studied. Full elution of gold cyanide using dynamic method of elution was achieved.
