Abstract: A process for recovering copper from chalcopyrite is disclosed. The process includes oxidising sulphur in chalcopyrite with a solution under predetermined contact conditions and thereby releasing at least part of the copper in the chalcopyrite into the solution as copper ions. The process includes a subsequent step of reducing sulphur in a solid product from step (a) to a minus two, ie. sulphide, valence state with a solution under predetermined contact conditions. The process further includes a subsequent step of oxidising sulphur in a solid product from step (b) with a solution under predetermined contact conditions and thereby releasing at least part of the remaining copper in the solid product into the solution as copper ions. The process further includes recovering copper from one or more of the solutions from steps (a) and (c).

Abstract: A method of leaching a metal value from a heap of a metal-containing ore and a heap leaching operation are disclosed. The method includes establishing a downward flow of a leach liquor through a section of the heap by supplying the leach liquor onto a top surface of the section and allowing the leach liquor (containing metal values in solution) to drain from a lower part of the section. The method is characterised by supplying the leach liquor onto the top surface of the section at a flow rate that is sufficient so that the downwardly flowing leach liquor saturates the section of the heap.

Abstract: Procedimiento para la lixiviación de un valor de metal procedente de una pila de un mineral que contiene metal. El procedimiento comprende establecer un flujo descendente de un licor de lixiviación a través de una sección de la pila suministrando el licor de lixiviación en la superficie superior de la sección y permitiendo que el licor de lixiviación (que contiene valores de metal en la solución) se filtre desde una parte inferior de la sección. El procedimiento está caracterizado porque se suministra el licor de lixiviación en la superficie superior de la sección con un caudal suficiente para que el licor de lixiviación que fluye en dirección descendente sature la sección de la pila.
