Abstract

Un metodo de lixiviacion de oro segun la presente invencion es un metodo para lixiviar el oro contenido en materias primas que contienen oro y azufre, como minerales de sulfuro o productos intermedios de refinacion obtenidos sometiendo los minerales de sulfuro a un tratamiento de refinacion, comprendiendo el metodo: una primera etapa de lixiviacion de lixiviar una parte del oro en las materias primas para obtener un residuo lixiviado que contiene azufre y el oro restante; una etapa de retirada de azufre de retirar azufre en el residuo lixiviado; y una segunda etapa de lixiviacion de lixiviar al menos una parte del oro restante en el residuo lixiviado despues de la etapa de retirada de azufre.A gold leaching method according to the present invention is a method for leaching gold contained in raw materials containing gold and sulfur, such as sulfide minerals or refining intermediates obtained by subjecting the sulfide minerals to a refining treatment, comprising the method: a first leaching stage of leaching a part of the gold in the raw materials to obtain a leached residue containing sulfur and the remaining gold; a sulfur removal step of removing sulfur in the leached residue; and a second leaching step of leaching at least a portion of the remaining gold in the residue leached after the sulfur removal step.
