dc.description.abstract | The present work aims to evaluate the possibility of achieving an environmental and economic valorisation of Mn-wastes through their recycling for concrete production. The study area is located in the Spanish sector of the Iberian Pyrite Belt (IPB), where there are numerous abandoned mine-waste dumps, resulted from exploitation of manganese mines. The methodological approach included field surveys for elaborating an inventory and a general map of all the abandoned exploitations, remote sensing methods for identifying old mines and for estimation of affected areas; and laboratory analyses for characterizing the mine wastes regarding evaluation of their potential as filler for concrete production. The obtained results indicated the existence of 149 mines, representing a total affected area of 235 ha. Among these waste dumps, about eleven of them have more than 10 000 m3 of Mn-gangue with chemical composition compatible with the normative for concrete production. The recycling of such wastes may accomplish two main purposes: to supply the market with low cost aggregates and, simultaneously, to contribute for the environmental rehabilitation of the affected areas. | por |
