Abstract: Bauxite mining has been carried out around Poços de Caldas, Minas Gerais, since the 1940s. Companies operating in the region pioneered land rehabilitation in Brazil, conducted since the early 1980s. Different procedures of recontouring, runoff drainage, soil preparation and vegetation planting were employed. This research aims to evaluate current environmental rehabilitation practices employed in the region, in order to identify possible deficiencies, investigate probable causes of these deficiencies and preve… Show more

“…Thus the recovery of mined areas and areas under the influence of bauxite mining is relatively rapid (Fonseca, 2021). Generally, after bauxite exploration, mining companies carry out topographic reconfiguration, transposition of the topsoil that was removed and stored before the activities, soil preparation, fertilization, and fencing of the area (Balestrin et al, 2019;Melo & Sánchez, 2020;Balestrin et al, 2020;Martins et al, 2020). In addition, to ensure sustainability, mining companies carry out restoration actions both in mined areas and in compensation areas, aiming at environmental recovery, either through active restoration techniques such as seedling planting, direct seeding, green manure and nucleation or by natural regeneration (Martins, 2018;Martins et al,2020;Cosimo et al, 2021;Fonseca, 2021;Martins et al, 2022).…”
