| Abstract Scope |
In the mining district of Zimapán, tons of mining waste from ore beneficiation plants are accumulated in urbanized areas. This study reports the characterization of such mineral solids to establish the distribution of potentially toxic elements at different particle sizes, as well as the calculation of cut-off grades that allow the classification of the residual dust as a source of secondary extraction. The analysis conducted through ICP showed a high concentration of Fe. However, the calculation of enrichment factors determined that it is an element associated with the parent rock, as corroborated by XRD and SEM-EDS techniques, which confirmed the presence of Hedenbergite and Cubanite in the mineral matrix. On the other hand, elements such as Ag and Pb contain an appropriate concentration to be considered as sources of secondary extraction and potentially toxic elements, so their extraction involves feasible reintegration with lesser environmental impacts. |
