WebEl objetivo del estudio fue determinar la presencia de microorganismos tales como Aciditiobacillus thiooxidans y ferrooxidans, en áreas mineras de La Rioja. Este tipo de bacterias, presenta una fuerte acción de oxidación sobre los minerales sulfurados y sus metales, generando H2SO4 y (SO4)3Fe2, componentes fundamentales del drenaje ácido. WebBiotechnological applications for metal recovery have played a greater role in recovery of valuable metals from low grade sulfide minerals from the beginning of the middle era till the end of the twentieth century. With depletion of ore/minerals and implementation of stricter environmental rules, microbiological applications for metal recovery have been shifted …

WebBio-cyanidation, a viable alternative of hazardous cyanide, is a promising approach for effective and relatively safe extraction of gold. For the first time, corn steep, a waste of corn processing plants has been used as an effective medium ingredient for the production of Bio-CN to develop cost-effective and environmentally friendlier approach for gold recovery. WebThe most-studied leaching bacteria are from the genus Acidithiobacillus. Acidithiobacillus ferrooxidans and A. thiooxidans are acidophilic mesophiles and together with the moderate thermophile, A. caldus, they belong to the Gram-negative γ-proteobacteria [25].The A. ferrooxidans has been considered as a model biomining microorganism [17, 22] and its …
