Abstract

Se caracterizaron mineralógicamente dos muestras de galena, pasante malla 200 y 325, provenientes del proceso de oxidación bacteriana mediante la utilización de una cepa compatible con Acidithiobacillus ferrooxidans. Los experimentos se realizaron previa adaptación de los microorganismos sobre el mineral como única fuente de energía. Para cada ensayo se hizo además blanco (abiótico) y réplica. Se midió pH y Eh diariamente durante 21 días, tomando muestras cada 4 días para el monitoreo mineralógico del proceso. La muestra -325 oxidó completamente, mientras que la -200 mostró oxidación parcial. La anglesita (PbSO4) fue el principal producto del proceso.
