As one of leaders of elution of gold stripping industry, SBM always seeks innovation & excellence.
for manufacturing elution column for processing of gold AARL Carbon Stripping System Operation: Elution. 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.

Dec 12, 2018· At a temperature of 80C all of the elution of gold from the carbon is being done by the alcohol. All alcohol based stripping systems recycle the alcohol in a permanent loop through a column of carbon which is wetted by cyanide solution. These systems only operate while alcohol or alternative organic complexes are present.

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
