Abstract
Que comprende: un metodo para recuperar oro a partir de minerales de oro conteniendo pirita que consta de: un pre-tratamiento de la primera etapa para preparar minerales de oro conteniendo pirita; una segunda etapa para calentar los minerales de oro de al menos 450 °C en una atmosfera inerte, para pirolizar la pirita a sulfuro de hierro (II) y azufre elemental, y que no contiene un proceso de tostacion oxidante; una tercera etapa para contactar los minerales de oro asi obtenidos por el proceso de pre-tratamiento, con un liquido de lixiviacion de oro conteniendo iones de cloruro, iones de bromuro e iones de hierro, mientras se suministra un agente oxidante para lixiviar el componente de oro en el mineral; una cuarta etapa en la que, despues de anadir a la solucion obtenida por lixiviacion del componente de oro en la tercera etapa, se anade un agente oxidante para ajustar el potencial de oxidacion-reduccion de al menos 520mv, lo que reduce la cantidad de iones de cobre monovalentes en lixiviado de oro; y un quinto paso en el que el oro en el lixiviado de oro obtenido en la cuarta etapa es adsorbido por carbon activadoComprising: a method for recovering gold from pyrite-containing gold ores consisting of: a first-stage pre-treatment to prepare pyrite-containing gold ores; a second stage to heat the gold ores to at least 450 ° C in an inert atmosphere, to pyrolyze the pyrite to iron (II) sulfide and elemental sulfur, and which does not contain an oxidative roasting process; a third stage to contact the gold minerals thus obtained by the pre-treatment process, with a gold leaching liquid containing chloride ions, bromide ions and iron ions, while supplying an oxidizing agent to leach the component of gold in ore; a fourth stage in which, after adding to the solution obtained by leaching the gold component in the third stage, an oxidizing agent is added to adjust the oxidation-reduction potential of at least 520mv, which reduces the amount of ions monovalent copper in gold leachate; and a fifth step in which the gold in the gold leachate obtained in the fourth stage is adsorbed by activated carbon
