Ore processing – Waihi Gold

In contrast, by the time the carbon reaches the first adsorption tank it has recovered most of the gold and silver from solution. This 'loaded' carbon is then pumped to the elution circuit (6) where the gold and silver is washed off with superheated water. The washed solution, called pregnant eluate, is passed to the electrowinning circuit (7).

All things considered my take would be you decide what cut off is acceptable for you. If your gold balance overall dictates that you do a 4 or 6 or 12 ton elution per day, then your elution should be done in the same day to maintain the inventory balance- in a Zadra system 18-20 hrs recycle is not uncommon even honouring all metallurgical parameters- it also depends on the cell activity, frame ...
