Abstract
La presente invencion se concentra en el metodo para la remocion de impurezas, tales como telurio y bismuto, de concentrado de oro que contiene sulfuros. De acuerdo al presente metodo, las impurezas son lixiviadas del concentrado de oro con la ayuda de una solucion acuosa acidica, a una elevada temperatura, mediante lo cual las impurezas se disuelven y el oro se queda en el concentrado.
