Abstract

Se revela un método para la lixiviacion en pila de un mineral que contiene calcopirita. Se introduce una solucion ácida que contiene bacterias oxidantes dehierro o azufre a una pila que contiene mineral de calcopirita que se ponga contacto con ese mineral. Dicho contacto liberará el cobre del mineral. Duranteeste procedimiento, se introduce un gas que contiene oxígeno a la pila como fuente de oxígeno para las bacterias. Se introduce el gas que contiene oxígeno a lapila con la temperatura y saturacion bajo control para mantener una porcion sustancial de la pila a una temperatura tal que las bacterias termofilas lixivienla calcopirita a una velocidad economicamente aceptable. También se revela un sistema de lixiviacion en pila (1) que opera de acuerdo con el método. También sedivulga un dispositivo para la lixiviacion en pila que incluye: a) Una pila de un mineral que contiene calcopirita, b) Un sistema de irrigacion de la solucionácida, c) Un sistema de recoleccion del lixiviado. d) Unsistema de aireacion para introducir un gas que contiene oxígeno.A method for heap leaching of a mineral containing chalcopyrite is revealed. An acid solution containing iron or sulfur oxidizing bacteria is introduced into a cell containing chalcopyrite ore that contacts that mineral. Such contact will release the copper from the mineral. During this procedure, a gas containing oxygen is introduced into the cell as a source of oxygen for the bacteria. The oxygen-containing gas is introduced into the cell with the temperature and saturation under control to maintain a substantial portion of the cell at a temperature such that the thermophilic bacteria leach chalcopyrite at an economically acceptable rate. A heap leaching system (1) is also revealed that operates according to the method. It also sedivulgates a device for heap leaching that includes: a) A pile of a mineral containing chalcopyrite, b) A system for irrigating the acid solution, c) A system for collecting leachate. d) An aeration system to introduce a gas containing oxygen.
