Adding Value to Mine Waste through Recovery Au, Sb, and As: The Case of Aurifer...
Lemos, M.; Valente, T.; Marinho Reis, P.; Fonseca, R.; Guabiroba, F.; Mata Filho, J.G.; Magalhães, M.F.; Delbem, I.D.; Rebelo Diório, G.From the colonial era to modern times, gold mining has played a crucial role in shaping Brazil’s economy, culture, and landscape, particularly in the Iron Quadrangle region. Therefore, resulting waste has accumulated in tailings structures, either from deactivated circuits or plants still in production. The present study reveals the potential assessed based on a set of metallurgical tests, assuming specific sce...
Hydrochemistry, Elements Distribution and Their Potential Recoveries in Gold Me...
Lemos, M.; Valente, T.; Marinho Reis, P.; Braga, A.S.; Fonseca, R.; Guabiroba, F.; Mata Filho, J.G.; Magalhães, M.F.; Silva, A.R.; Bhering, A.P.Recovering metals from mining wastewater is important in minimizing environmental pollution and maximizing resource efficiency. For this, a characterization step and understanding the oc-currence of metals and other compounds are essential. The present study focused on waters from different mining dams containing metals such as Au, Cu, Ni, Zn, and sulfates, located in the Iron Quadrangle region, (Brazil). The r...
