Ion exchange adsorption and elution for recovering gold

Ion exchange adsorption and elution for recovering gold

Jan 01, 2010 The pre-elution removed 99.7% of the copper from the resin, and only 2.7% of the gold, which would not be lost, as the pre-eluate would either be used as the leach feed solution (since it contains high thiosulfate), or the copper and gold could be …

The recovery of gold from ammoniacal thiosulfate solutions

Mar 01, 2004 Elution of gold and copper from a column of Dowex 21K (9.12 kg/t Au and 8.19 kg/t Cu) using the same eluant as for Fig. 5 (flow rate 2 BV/h). Sodium sulfite alone was also found to be very effective for gold and copper elution. However, copper hydroxide precipitated in the eluate solution and this was prevented by the addition of ammonia.

Loading and Elution of Gold Thiosulfate from Anion

Loading and Elution of Gold Thiosulfate from Anion

A new elution process has been developed for the recovery of gold thiosulfate from ion exchange resins. This is a synergistic system which utilises a base eluent, such as nitrate or trithionate, along with an additive that improves the elution of gold. The use of the additive enables lower eluent concentrations to be adopted, as well as weaker eluents such as chloride.

TECHNICAL PAPER Purolite

Copper loads onto carbon to a certain extent even when adequate levels of free cyanide is maintained in solution, and the amount of loaded copper is often equivalent to or greater than the amount of gold loaded. However, copper could be eluted from the carbon with cyanide solution at room temperature prior to gold elution at high temperature(5).

Evaluating a Dynamic Model for the Competitive Elution of

Aug 06, 2019 The competition coefficients are parameters which indicate the extent to which the base metals affect the elution of gold. At high copper loadings the desorption behavior of copper and gold changed, and an increased adsorptivity was detected. It was postulated that this was mainly due to the formation of copper-gold polymeric chains.
