Production of Gold - West ia University

Gold is adsorbed onto the activated carbon. The filtrate is then sent to the elution vessel, V-401, where the elution process begins. The gold is eluted into a water solution from the carbon by the American-Anglo Research Laboratories (AARL) method, leaving the barren carbon behind. Figure 5 shows the carbon adsorption and AARL elution processes.

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 ...

Mercury in Gold Processing - ScienceDirect

Jan 01, 2016· Elution. Some of the mercury may be stripped from carbon during intensive acid-washing. The Jerritt Canyon plant in the Carlin area in Nevada reportedly had ∼25 g/t Hg in the ore, and a 20–30% nitric acid wash at 80 °C for 2 h removed 60–70% of the mercury, with the spent acid being returned to the leach circuit (Marsden and House, 1992).
