Analysis of magnetic particles from mining waste
Abstract
One of the potential threats of mining waste is the dispersion of toxic dust, which can be inhaled by people, putting their health at risk. This research focuses on the study of magnetic particles contained in a sample of mining waste from the municipality of Mineral de la Reforma Hidalgo, Mexico. In this study, a representative sample was attricted and dried to perform a sieve granulometric analysis. Subsequently, a magnetic separation of each sample was carried out to determine the concentration of magnetic particles. Strong magnetic and moderately magnetic particle samples were obtained, these were analyzed by X-ray diffraction, infrared spectroscopy and scanning electron microscopy. The results of this study will serve to determine the feasibility of building a magnetic separator that allows improving the treatment process of these wastes, in order to reduce the impact they have on the environment.
