Abstract

La invencion proporciona un metodo para lixiviar un mineral, el metodo que comprende los pasos del metodo de: curar el mineral silicato de zinc a ser lixiviado mediante la aplicacion de una solucion acuosa de un acido debil, produciendo un mineral curado; lixiviar el mineral curado a presion atmosferica mediante la aplicacion de una solucion de carbonato de amonio que contiene amoniaco libre, produciendo una solucion de lixiviacion cargada; y pasar la solucion de lixiviacion cargada a los medios para la recuperacion de zincThe invention provides a method for leaching a mineral, the method comprising the steps of the method of: curing the zinc silicate mineral to be leached by applying an aqueous solution of a weak acid, producing a cured mineral; leaching the cured mineral at atmospheric pressure by applying an ammonium carbonate solution containing free ammonia, producing a loaded leaching solution; and pass the loaded leach solution to the zinc recovery media
