Abstract

La invención se refiere a un proceso para el pretratamiento de una carga para un biorreactor de lixiviación en pilas de superficie no agitada mediante la aplicación en secuencia de soluciones de pretratamiento primera y segunda a una carga para un biorreactor de lixiviación en pilas de superficie no agitada, en el que la primera solución posee un contenido de hierro superior a 5 g/l y un pH inferior a 2, y la segunda solución contiene una población microbiana sustancialmente superior. La invención se refiere además a métodos para adaptar una población microbiana para utilizar en un biorreactor de lixiviación en pilas de superficie no agitada.The invention relates to a process for the pretreatment of a charge for a leach bioreactor in unwanted surface piles by sequential application of first and second pretreatment solutions to a load for a leach bioreactor in un agitated surface piles. , in which the first solution has an iron content greater than 5 g / l and a pH less than 2, and the second solution contains a substantially higher microbial population. The invention further relates to methods for adapting a microbial population for use in a leach bioreactor in non-agitated surface batteries.
