PROCESO PARA EL PRETRATAMIENTO DE UNA CARGA EN UN BIOREACTOR DE LIXIVIACION EN PILAS DE SUPERFICIE NO AGITADA QUE COMPRENDE APLICAR EN SECUENCIAS SOLUCIONES A DICHA CARGA EN QUE UNA PRIMERA SOLUCION POSEE HIERRO SUPERIOR A 5 G/L Y UNA SEGUNDA SOLUCIO

摘要

The invention relates to a process for the pre-treatment of feed to a non-stirred surface heap leach bioreactor by applying in sequence first and second pre-treatment solutions to a feed to a non-stirred surface heap leach bioreactor, in which the first solution has an iron content greater than 5 g/l and pH below 2, and the second solution contains a substantially higher microbial population. The invention further relates to methods of adapting a microbial population for use in a non-stirred surface heap leach bioreactor.
