exchange resins, mainly employing resin-in-pulp (RIP) technology . Ion exchange resins have several advantages over activated carbon for the recovery of gold, as discussed in a number of previous publications [2,4,6,7]. The main advantages are as follows: i. Chemical regeneration: ion exchange resins are stripped at low temperatures and do not
Development of Dowex-Minix gold-selective resin Earlier work showed that anion-exchange resins have some distinct advantages over activated carbon for the recovery of gold from cyanide leach liquors1. Resins have potentially higher loading capacities and loading rates, are less likely to be poisoned by organic matter such as lubricants and
Ion exchange resins were investigated for the effective recovery of platinum, palladium, and gold from a pregnant cyanide heap leach solution. Screening results indicated that strong-base anion exchange resins proved to be most effective in the recovery of these metal cyanides.
DuPont anion exchange resins, such as AmberSep™ 21K XLT Resin, are commonly used in the recovery of gold from spent plating bath solutions. Generally, the loaded resin will absorb up to 60 oz of gold per cubic foot (60 g/L) and the gold is recovered by thermal decomposition (fuming).
In this paper one strong acidic, one strong basic and one weak basic ion-exchange resins, considered as exhausted in an industrial demineralizing plant, are screened for gold recovery from cyanide
A600OH An anion resin in the OH- form maintains a high pH and helps prevent formation of hydrogen cyanide gas. Capacity for gold is 100 ounces per cu. ft. maximum. This anion resin is also used in two-step demineralization systems with the cation resin in the hydrogen form.

ORIGINAL ARTICLE The recovery of gold from the aqua regia leachate of electronic parts using a core–shell type anion exchange resin P. Cyganowskia,*, K. Garberaa, A. Les´niewiczb, J. Wolskaa, P
Application of ion-exchange resins to the recovery of gold is described. Significant developments around gold-selective anion-exchange resins and the commercialization of at least two of these products have made resin-in-pulp (RIP) available as an alternative to CIP for the upgrading of gold
The incineration of the resin can be carried out by precious metal recovery companies at a cost equal to a small percentage of the overall value of the gold.Certain base metals, such as copper, nickel, cobalt, and zinc, form anionic complexes with strong affinities for the strongly basic resins.
process lacks a proven in-pulp method for recovering dissolved gold. Anion exchange resins offer a possible route for in-pulp recovery. This thesis describes work aimed at evaluating the effectiveness of commercially available anion exchange resins for the recovery of gold
A gold selective ion exchange resin and process for the recovery of gold from solutions thereof is described. The resin has a macroporous structure and functional groups selected from alkylamine groups wherein the alkyl chain has between 3 and 6 carbon atoms, preferably tributylamine groups. The functional group content of the resin is from 0,4 mmol/g to 1,8 mmol/g and the water retention
