the final product in the electrowinning process. Based on the understanding of the kinetics of the elution, four parameters, namely temperature, flow rate, free caustic soda concentration and cyanide strength, were evaluated first for the elution process. Experimental runs on the plant scale did prove that the first three parameters are the

The gold can then be removed from the solution by electrowinning onto steel wool cathodes (refer ‘Electrowinning and Smelting’ module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence gold adsorbing ...

During this stage a 2% caustic/3% cyanide solution mixture is re-circulated through the loaded carbon in the elution column until such time as a predetermined “top of column” temperature is reached. By this time most of the gold and silver on the carbon will have been desorbed into solution and both the carbon and the solution will have reached an optimum temperature for the subsequent ...

Carbon in pulp - Wikipedia

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Elution of Mercury Silver Gold from Anion Exchange Resin

Gold elution of 94 to 95 pct was obtained in 6 h with 2M NaClO4 in batch tests, and 79- to 89-pct elution was obtained in 6 h in 24 resin BV in column tests. In the batch elution tests, some silver was removed from the resins with H2SO4, and some gold was removed with strong chloride solutions; however, the silver and gold were not soluble in ...

When a highly-selective resin is not required, AmberSep™ 21K XLT Strong Base Anion Resin can be used to capture the gold since gold extracted by cyanidation is in the form of anionic aurocyanide complex (Au(CN) 2-). Elution from the resin can be achieved with a more strongly adsorbed anion; zinc cyanide or thiocyanate are commonly employed.

Elution - Wikipedia

In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions.. In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or "bound to", an adsorbent in a liquid chromatography column. The adsorbent, a solid phase (stationary phase ...
