El beneficio del oro en minerales refractarios de la Faja Pirítica

Abstract

La Faja Pirítica Ibérica, en la que se ubican más de 70 yacimientos de sulfuros masivos volcanogénicos, constituye una provincia metalogenética a escala mundial, con unos recursos considerables en azufre, hierro y metales básicos y en menor medida oro y plata. El Instituto Geológico y Minero de España (IGME), en el sector de las investigaciones minero-metalúrgicas, ha participado en diversos proyectos encaminados a la recuperación del oro de este tipo de mineralizaciones. Una buena parte de su labor investigadora, en el ámbito de la hidrometalurgia, se ha centrado en la búsqueda de tratamientos alternativos de las menas auríferas refractarias, tan características de la Faja Pirítica, contemplando simultáneamente la recuperación de los metales básicos y del oro contenido en dichas menas, así como la extracción de cualquier otro metal minoritario, susceptible de beneficio económico, que pudiera contribuir a la reducción de los costes de explotación. A tal fin, se han combinado métodos de tratamiento tradicionales, como la cianuración, con otros de carácter innovador, tales como la lixiviación ácida a presión, la tostación oxidante, la lixiviación férrica a presión atmosférica y la biolixiviación.
