A mine tailing deposit is defined as a finely ground solid, between sand and silt, that is discarded from mining operations. These residues are composed of a fine suspension of solids and made up of the same material present in-situ in the deposit, from which the fraction with the valuable mineral has been extracted (MEND, 2004; Verburg et al., 2009).
