Abstract
Que comprende un pretratamiento incluyendo 1) preparacion de la mena de oro conteniendo pirita, 2) calentamiento de la mena de oro bajo una atmosfera no oxidante a 450�C o mas, con el fin de que la pirita en la mena de oro se pirolice en sulfuro de hierro (II) y azufre elemental, donde el pretratamiento no incluye la oxidacion por tostacion, y 3) puesta en contacto de la mena de oro pretratada con una solucion de lixiviacion de oro, conteniendo los iones de haluro y los iones de hierro, mientras se suministra un oxidante para lixiviar el componente de oro en la mena. La velocidad de la lixiviacion del oro es incrementada sin el uso de reactivos toxicos, tal como el gas cianuro, tiourea, tiosulfato y halogeno, mientras se suprime la generacion de dioxido de azufreWhich comprises a pretreatment including 1) preparation of the gold ore containing pyrite, 2) heating the gold ore under a non-oxidizing atmosphere at 450 ° C or more, in order that the pyrite in the gold ore becomes pyrolyzed in iron (II) sulfide and elemental sulfur, where the pretreatment does not include oxidation by roasting, and 3) contacting the pretreated gold ore with a gold leaching solution, containing halide ions and gold ions. iron, while supplying an oxidant to leach the gold component in the ore. The leaching rate of gold is increased without the use of toxic reagents, such as cyanide gas, thiourea, thiosulfate and halogen, while suppressing the generation of sulfur dioxide.
