Elution stage. During this stage the gold and silver desorbed off the carbon during the preheat .* is washed out of the column into the eluate tank. This stage takes 2 1/2 hours and involves the use of 5 bed volumes of potable water (21.6 cubic metres). The critical factor during this stage is temperature. It has been found that the optimum top of
the CIP can be stripped together with gold in the elution process. Depending on their concentration in the pregnant solution, cathodic deposition occurs.
A powerful reducing agent such as hydrazine monohydrate is added to standard elution solutions such as NaOH NaCN solutions with or without alcohol, thereby substantially increasing the elution kinetics of gold and silver.
elution process gold_Elution In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent as
leaching, adsorption, elution and regeneration would typically make up some 15% of total operating cost, represent the primary gold recovery process
Apr 02, 20160183;32;In all plant circuits, the carbon activity quickly deteriorates from stage to stage but the reasons why it should do so are complex. It is known that the carbon activity is enhanced by lower pH, higher temperature; the presence of Ca2*, Mg2*, Na*; and by small particle size. On the other hand, its activity is

This process continues until the carbon has been stripped. The cathodes (wire wool now plated with gold and other metals) are removed and placed in acid. The acid burns off the wire wool and other metals such as copper and leaves a sediment of gold and solution of acid and dissolved silver. The acid and silver are drained off after which the gold
