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).
