ION EXCHANGE RECOVERY OF GOLD AND SILVER FROM

1987-1-1  GOLD METALLURGY The elution of silver from strong-base resins has not been studied in detail. As noted previously in the U.S. Bureau of Mines process, silver is displaced, prior to the gold elution, by means of an acldltiled NaCl solution. Riveros (1985) found that silver is much easier to elute than gold.

The pretreatment of gold-loaded activated carbon with a relatively strong sodium cyanide solution prior to elution with deionized water at 90 to 125i?½Chas been shown to have a most beneficial effect on the elution of gold. The findings emphasize the important role played by the calcium cation and the hydroxyl anion in effecting efficient elution of gold.

Elution and electrowinning of gold from gold-selective ...

Abstract The recovery of gold was investigated using the new gold-selective resin, Minix, which was developed by Mintek. The most suitable elution technique for this resin was found to be an acidic thiourea eluant. The gold-selective adsorption characteristics of Minix, particularly its high selectivity against cobalt and iron cyanides, make it possible to use the advantages of the thiourea ...

Elution and spectrophotometric determination of gold

The method was found suitable for determination of gold after its separation from other metals by extraction chromatography on supports treated with liquid anion-exchangers. Mixtures of gold(III) and iridium(IV) were separated by column extraction chromatography on silica treated with a tri-n-octylamine (TOA) salt. A mixture 2.25M in hydrochloric acid and 5M in nitric acid was used for elution ...
