Abstract

Se describe un sistema y metodo para mejorar la cinetica de lixiviacion y la recuperacion durante la lixiviacion atmosferica anterior de un sulfuro de metal. En algunas modalidades, el metodo puede comprender los pasos de: (a) producir un concentrado de sulfuro de metal [34] por flotacion; (b) mover el concentrado de sulfuro de metal producido [34] a por lo menos una camara [22a] de por lo menos un reactor tal como una autoclave [20]; (c) lixiviar el concentrado de sulfuro de metal producido en por lo menos una camara [22a] en la presencia de oxigeno [82] a una presion y/o temperatura superior a la ambiente, y en la presencia de medios de molido parcialmente utilizados [25] y/o nuevos [92] dentro de por lo menos una camara [22a]. Tambien se describen sistemas [10] y un aparato [20, 200] para practicar el metodo antes mencionado
