Roasting of refractory gold - ores. Refractory gold-ores are characterized by low gold recoveries in direct cyanide leaching. Gold particles are either embedded in sulfide components or absorbed on carbon surfaces during the leaching process. Oxidizing roasting of such ores prior to leaching is an effective step to increase gold recovery ...
