- Abstract
In the present study, intermediate products formed during gold-bearing pyrite biooxidation by moderately thermophilc bacteria at 42℃ were studied by combined using XRD, Mössbauer and Raman spectroscopy. Biooxidation slowdown since 8th day showed that some intermediate products might hampered the further oxidation of gold-bearing pyrite. XRD and Mössbauer analysis confirmed there was no jarosite formed in the biooxidation. Raman analysis confirmed the accumulation of elemental sulfur on the gold-bearing pyrite surface led to the slowdown of the biooxidation.
