A process for the recovery of gold from a potassium iodide-iodine solution
is provided. The gold is precipitated from the solution using a weak
acid, (e.g. ascorbic acid), a buffer, (e.g. sodium bicarbonate), and a
dye. The precipitate is then removed from the solution resulting in the
recovery the gold precipitate and the potassium iodide-iodine solution.
