Tratamiento de drenaje ácido de mina con el uso de zeolita natural a escala experimental

Abstract

El presente proyecto de investigación se realizó en el Instituto Nacional de Investigación Geológico Minero Metalúrgico (INIGEMM) con un total de 40 litros de agua del Drenaje Ácido de Mina (AMD, por sus siglas en inglés) recolectados en la Quebrada “El Panteón”, Parroquia Torata, Cantón Santa Rosa, Provincia de El Oro. El AMD se trató mediante un sistema de tratamiento que consistió en una serie de dos columnas de lixiviación conectadas por flujo a través de una bomba peristáltica, las cuales contenían materiales reactivos tipo Sustrato Alcalino Disperso (DAS, por sus siglas en inglés), y la adición de zeolita natural como un medio filtrante. En el sistema de tratamiento se realizaron 12 mediciones de conductividad y pH, mientras que, para el análisis de metales (Al, Fe, Cu, Pb, Zn, Mn y Cd) y el anión SO42- se realizaron cuatro mediciones. El valor de pH promedio de AMD tratado fue 8.03 y la conductividad promedio obtenida fue de 3254μS/cm. La eficiencia de remoción promedio tratada fue: Al (97.81%); Fe (99.79%); Cu (91.42%); Pb (83.33%); Zn (99.84%); Mn (96.14%); Cd (88.54%) y SO42- (51.47%). El sistema presenta una alta remoción de metales conforme a los resultados obtenidos, por lo que la descarga cumple con la normativa ambiental nacional, exceptuando el anión SO42-.
