Abstract

<p>Se describe un método para meiorar la cinética de lixiviación y la recuperación durante la lixiviación atmosférica o por encima de la atmosférica de un sulfuro de metal. También se describe un sistema para practicar el método antes mencionado. Tambien se describe un aparato para practicar el método antes mencionado. Se describe además una nueva composición de materia que se forma por el método antes mencionado, y que puede ser utilizado en el sistema y aparato. La nueva composición de materia puede exhibir la cinética de lixiviación mejorada, y puede tener alguna utilidad en las artes semi-conductoras incluyendo unos dentro de materiales fotovoltaicos.</p>
