Once the gold is dissolved in the cyanide solution, the mixture undergoes a process called adsorption, where activated carbon is used to capture the gold from the solution. The gold-laden carbon is then subjected to a series of steps to recover pure gold, including desorption and electro-winning, where electricity is used to precipitate gold from the solution. The final product is pure gold, often in the form of bars or nuggets.
