Abstract: A process for recovering gold from a gold-containing raw material, comprising leaching the gold-containing material with an aqueous solution comprising elemental bromine and bromide source to form a pregnant leach solution with the gold dissolved therein; separating said pregnant leach solution from the gold-depleted raw material, removing elemental bromine from said pregnant leach solution, extracting the gold from the pregnant leach solution in an acidic environment into an organic extractant, to form a gold-loaded extract and bromide-containing raffmate, stripping the extract with an alkaline aqueous solution to form a gold-bearing aqueous solution, generating gold (Au0) and treating bromide-containing stream(s) to produce recyclable elemental bromine.
