Correlación del potencial óxido reducción y la población bacteriana durante el estudio de biolixiviación de sulfuros de cobre

Abstract: Se estudio la correlación de las variables población bacteriana y potencial de óxido reducción (ORP) en la biolixiviación de minerales sulfurados mediante cepa bacteriana de Acidithiobacilus Ferrooxidans aisladas a partir de efluente ácido de mina, buscando la solubilización del cobre y la liberación del oro presente en un mineral con sulfuros superior a 80%. Las variables de experimentación fueron: La densidad de pulpa a 1, 2 y 6 % (W/V), concentración de sulfato ferroso como parte del medio 9k de 0, 3, 6, 9 … Show more

“…This is because antimony and its oxides are volatile at the typical temperatures under which such processes operate. Despite such behavior, during industrial operation, a significant portion of antimony is retained in the condensed phases [18][19][20]. Furthermore, the elucidation of the mechanisms of the decomposition of stibnite (Sb 2 S 3 ) is relevant for the control of antimony content in both the calcine and condensed phases.…”

“…In this regard, decreases in potential of up to 33 mV have been reported with a one-unit increase in pH [4]. However, real-time potential monitoring offers many advantages [5].…”
