Determinación De Posible Drenaje Ácido De Mina Y Caracterización De Jales Mineros Provenientes De La Mina Cerro De Mercado, Durango, México

Abstract: La mina Cerro de Mercado, ubicada en el estado de Durango, México, ha almacenado jales durante el proceso de extracción de hematita y magnetita durante aproximadamente 80 años. La presente investigación tuvo como objetivo llevar caracterizar los jales de la presa Boleo Estrella de la mina Cerro de Mercado y determinar el potencial de generación de drenaje ácido, considerando la Norma Oficial Mexicana NOM-141-SEMARNAT-2003. El muestreo se realizó de acuerdo con la Norma Mexicana NMX-AA-132-SCFI-2006 y se obtuvi… Show more

“…According to the Tables 2 and 3 , there are potential toxic elements such as arsenic and lead present in the samples. Furthermore, in some samples where sulfur was detected, however, analyzing the contrast of the images, it is noted that the surrounding particles that contain this element are mostly carbonates (calcite, magnesite, smithsonite, principally), so in the presence of water, they can neutralize to sulfuric acid generated by sulfur and thus avoiding the formation of acid drainage and the leaching of toxic metals, which is also justified with the pH values obtained (García et al, 2017 ; Salas Urviola et al, 2020a , 2020b ).…”

“…The samples have a slightly neutral-alkaline pH, this may be due to the fact that there are minerals with neutralization capacity such as carbonates and a low concentration of acid-forming components such as pyrites (Armienta et al, 2004 ; Corona Sánchez et al, 2021 ; Espinosa et al, 2009 ). Due to these values, it can be said that there is also a low mobility towards aquifers of dangerous toxic elements because it is necessary to have acid conditions in the environment for this to happen (Salas-Luevano et al, 2021 ; Salas Urviola et al, 2020a , 2020b ). It should be noted that the survey was carried out from the top to the base of the dam (Figure S1 ), beginning with point z-1 and as the numbering increases, it is closer to the base with point z-10.…”

“…Los desechos de la mina en la presa de relaves se han erosionado, creando una sobrecarga a su alrededor, además, este proceso produce aguas residuales altamente ácidas con altas concentraciones en Pb, Fe, Cu y Zn, así mismo la calidad del agua en los arroyos se vio afectada con pH bajo (pH<4) encontrándose presencia de metales pesados que superaron los límites máximos permisibles del agua potable (6). Por otra parte, el drenaje ácido de mina es menos probable cuando el CaCO3 es alto ya que neutraliza la presencia de los sulfuros en el suelo (7).…”
