Recover Gold from Cyanide Waste Water of Gold Plated by 353E Resin

The method for the recover gold from cyanide waste water og gold plated by 353E an amion exchange resin with double function groups are reseached in the paper. The results indicate that Au(CN)₂^- complex anion can be strongly adsorbed onto the 353E resin in the range of pH 8-14 in cyanide medium. It is very easy to elute the gold from the loaded resin using 3% (υ/v) sulphuri acid-7% (ω/v) thiourea solution. At the same time the 353E resin has better adsorptivity Enlarge test of anion-exchange column is identical in experimental result of a little ion-exchange column. Provide scientitic basis for further industrial recover gold.
