“…Calcite is the most important neutralizing agent because of its common occurrence in a wide range of geological environments and its rapid reaction rate (Lottermoser 2010). Paktunc (1999) stated that a waste material to be considered as having no AMD potential, it must contain at least 12 times as much calcite as pyrite. Carbonate minerals were, however, not determined by geochemical analysis in these samples: only silicate minerals, such as chlorite, feldspar, kaolinite, mica, quartz, zeolite, and opal-CT, were identified.…”

“…Balance de acidez y neutralización (ABA) de los jales del DIMITO El balance de acidez (ABA) se refiere al uso de las bases de datos geoquímicas con la finalidad de predecir el riesgo de la generación de acidez de un yacimiento o un sistema de resiudos mineros (Paktunc 1999;Jambor 2003;Price, 2009) valores más bajos de pH y las mayores concentraciones de sulfuros (e.g. EIII, EVIIl, VIII).…”

“…Finalmente, se calculó el potencial de neutralización (PN) y acidez (PA), así como su balance ácido-base (ABA), utilizando los programas Modan y mNP y el método de Paktunc (1998; e, incorporando las correcciones para los Al-silicatos aplicadas por Jambor et al (2004). El cálculo se basa en la composición geoquímica de elementos mayores, incluyendo los valores de azufre y carbono (Paktunc, 1999;Bouzahzah et al, 2014). Se calcula la composición normativa de los minerales: silicatos, carbonatos y sulfuros, los cuales son sucesivamente ponderados, con base en un índice estadístico de capacidad de generación de acidez (Paktunc, 1999;Jambor, 2003).…”
