Popis:	This study investigated Acidithiobacillus ferrooxidans induced mineral precipitation under the photocatalysis and non-photocatalysis of natural sphalerite. The bacterial activity and the Fe2+ concentrations were found to be remarkably influenced by the photocatalysis of natural sphalerite. As a result, K-jarosite was only detected in the photocatalytic treatment, which was estimated to be the result of higher bacteria activity under sphalerite photocatalysis; yet, NH4-jarosite formed in both treatments. Besides, the minerals in photocatalytic treatment had better crystallinity than those in non-photocatalytic treatment.
