Abstract
El problema del drenaje ácido de mina se hace especialmente tangible
en el agua embalsada en las cortas mineras de la Faja Pirítica Ibérica. Los
últimos estudios en investigación para la remediación se centran en el uso
de materiales alcalinos. En este trabajo se presentan los resultados de un
trabajo realizado con residuos de bajo coste, procedentes de la industria
papelera, para la recuperación de aguas ácidas. Se tomaron muestras de
agua en cortas mineras, y se sometieron a ensayos para comprobar el poder
de neutralización de diferentes residuos alcalinos (cenizas de combustión de
biomasa, cenizas de caldera de recuperación y lodos calizos). Se obtuvieron
resultados positivos para los tres reactivos, siendo los lodos calizos los que
mostraron valores más significativos
The problem of acid mine drainage is especially tangible in water stored in open pits in the Iberian Pyrite Belt. Recent research studies focus on remediation using alkaline materials. This work presents the results of an experiment carried out with low cost waste coming from the paper industry for the recovery of water and its subsequent use as irrigation. Few samples of acid mine drainage from open pits were collected and subjected to tests in order to verify the neutralizing power of the different alkaline residues (biomass combustion ash, recovery boiler ash and lime mud). Positive results were obtained for the three reagents, the lime mud showed the most significant values
