Modelización geoquímica de los serrines de granito

Resumo

Dimension stone industry is one of the leading economic potentials of Galicia Our study tries to answer at three of the basic expectations that the granite industry sector has outlined. These questions also possess a particular interest for the Administration: 1. The classification and characterization of the fines like a type of residuals and how this affects to their classification (inert / not inert) in a more specific way: 2. The identification of intrinsic properties of the fines so that, starting from them, allow obtaining of the fines some economic profit or, at least, a better integration in the productive cycle of the natural (dimension) stone. 3. The identification and study of viable applications from the technical and economic points of view that allow an evaluation of these wastes, transforming them in by-products of the process. According to the volume of granite fines annually generated in the district of O Porriño, it is necessary to look for applications that require large material volumes and short transport distances at the same time (sustainability approach). In that way, this investigation has been focused on the application of the same ones as barrier of waterproof and/or sealed landfills.
