    2016-5-31 · First, the gold is locked in sulfide mineral particles that must be oxidized to expose the gold for leaching. Second, the ore also contains preg-robbing carbon that will collect solubilized gold from the subsequent leaching circuit if the gold is not first removed. Both problems are addressed by roasting the finely ground ore in two roasters to produce a calcine with very low sulfur and carbon contents that is amenable to gold recovery in a conventional CIL (carbon and Leach) plant.
