Abstract

Procedimiento para el tratamiento y descontaminación de aguas ácidas que contienen metales disueltos y su conversión en fertilizantes que consiste en la combinación de tres procesos específicos: a) Eliminación selectiva del hierro y de la acidez del medio mediante la biooxidación de Fe (II) y precipitación con álcalis (Ca(OH){sub,2 , NaOH, KOH ó NH{sub,4 OH) de los compuestos de Fe(III). b) Aprovechamiento del elevado contenido en sulfatos de las aguas ácidas para la síntesis, mediante intercambio iónico, de K{sub,2 SO{sub,4 ó NH{sub,4 SO{sub,4 , libre de cloruros que pueden ser utilizados como fertilizantes o comercializados en otras aplicaciones. c) Recuperación de los metales contenidos en estas aguas: CU{sup,2+ , Al{sup,3+ , Zn{sup,2+ y Mg{sup,2+ . Este proceso se puede aplicar a aguas ácidas de diversas procedencias: instalaciones mineras activas o inactivas, cuencas fluviales, arroyos, lagunas, etc. que debido a su contacto con masas de mineral se encuentren contaminadas con ácido sulfúrico y metales pesados, así como instalaciones industriales que produzcan efluentes ácidos (ejemplo: industria galvanotécnica).
