The solution, which now does not contain gold, is then recycled back to the heaps. From the sorbtion columns gold is then desorbed from the activated carbon using a hot caustic solution, and then goes through an electrolysis operation where gold is deposited on cathodes, which are then smelted into dorè bars containing not less than 70% gold (along with copper, iron and silver).

contacting the carbon with a solution of sodium cyanide (0.1 to 2% by mass) and sodium hydroxide (0.1 to 2% by mass) at high temperatures (90120°C). This results in the reversal of the adsorption process with most of the gold desorbing from the carbon back into solution. This produces a small volume of solution with a high gold concentration.
