Evaluating acidithiobacillus ferrooxidans bacterial oxidation of sulphur compounds using ftir and x-ray diffraction assays

A native bacterial strain capable of oxidising ferrous iron and sulphur compounds was isolated from effluent and material from the La Maruja gold mine in the municipality of Marmato (Caldas); this was biochemically identified as being Acidithiobacillus ferrooxidans. This strain's ability to oxi...

Esta cepa fue evaluada en su capacidad de oxidar concentra­dos de sulfuros metálicos a dos diferentes concentraciones de pulpa y dos tamaños de partícula. Después de 15 días de biooxidación de los sulfuros se observó que, efectivamente, la bacteria mostró acción catalizadora sobre el proce­so de disolución del mineral.
