Elution - an overview ScienceDirect Topics

The original design of the stripping section required up to 288 h (12 days) for elution before achieving gold recovery. In the 1980s, a new stripping technique was developed, which takes from 12 to 24 h, a considerable improvement over the original design. Gold from the pregnant thiourea solution is recovered by transferring the solution from the elution section to holding tanks for an electrowinning section.

OPTIMIZING THE OPERATING CONDITIONS OF GOLD

2021-3-19  Base metals that have not been stripped during the elution will build up in the carbon and will affect the gold loading in the CIP process. The continuous decrease of gold content in the stream and the variability of flow rate and temperature affect the elution and

Electrowinning - ScienceDirect

2016-1-1  The elution rate of the gold from the carbon in to the eluate was limited by the relatively low temperature and due to the cell inefficiency, gold that was not plated was recycled to the carbon, further inhibiting the elution rate. These two effects resulted in elution cycle times in the range of 24–96 h.

1994-8-1  Elution efficiencies of around 100 per cent were also obtained in less than 4 hours during the batch elution of carbon at liquid-to-solid ratios of about 100. Lower liquid-to-solid ratios resulted in the re-adsorption of gold, probably owing to the oxidation of sulphide to polysulphide, with the resultant formation of gold complexes that were ...
