Modelling of the AARL elution process ScienceDirect

May 01, 1994· The influence of temperature on the equilibrium adsorption of gold and hydroxide ion at elution conditions was examined. Experiments were conducted for both single and multiple solute adsorption of gold and OH − ion at the temperaturesbetween 80 and 120°C. Two models were employed to model the equilibrium adsorption of each solute at the single solute level.

Strategies for the optimisation of gold processing plants

This is an excellent starting point to commence elution optimisation. Optimisation of the 125°C AARL elution circuit at a small high grade gold mine in PNG in 1996 increased the weekly stripping rate from 6 to 21 strips/week. This facility had been badly bottlenecking the rest of the plant as it regularly campaigned up to 30gpt Au and 200gpt Ag.

conditions, elution (desorption) of gold from the carbon occurs. The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures. If the temperature of a solution and carbon mixture is increased, the gold will readily desorb from the carbon into the solution. Temperature
