Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore MiningThe dissolved gold in solution is adsorbed onto activated carbon When the carbon is loaded with enough gold it is removed from the circuit and sent to elution where the adsorption process is reversed and the gold is stripped off the carbon back into solution, electrowon and smelted into bars.

Elution and Carbon Reactivation - Resource bookIs Extracting Gold from Printed Circuit Boards Possible

During the CIL process, gold is leached from the ore using an alkaline cyanide solution The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversedExtracting gold from a printed circuit board is definitely possible but the amount of the gold in the PCB has to be evaluated first The process involves a number of steps which have to be carried out carefully in order to get the desired results There are some instruments and acids involved in the process Necessary precautions must be taken before starting the procedure.
