? 2021 Elsevier B.V.Mining is one of the main economic activities in the Amazon region, contributing substantially to the economy of countries that share its territory. This activity, however, brings environmental aftermaths as vegetation suppression, soil destruction, hydrological instability, and faunal displacement, making restoration of degraded ecosystems a challenge. In this sense, the objective of our study was to present the economic importance, the main restoration methods, and the bottlenecks to obtain successful restoration trajectories in degraded areas by industrial mining in the Amazon. We listed eight possible relevant procedures for successful restoration after mining and discussed worldwide adopted restoration methods such as seedling planting, inducing natural regeneration, hydroseeding, and nucleation. Despite the great development of restoration methods after mining, there are still barriers to obtain inputs, which include seedlings, and qualified labor to plan and develop restoration projects. These issues come in addition to operational restrictions, technical incapacity, deficient or inflexible legal basis, and lack of law enforcement. We suggest the selection of key species for planting, associated with arbuscular mycorrhizal fungi and biochar, establishment of lists with ecological indicators and reference values, usage of organic waste, and monitoring through unmanned aerial vehicles with high sensors resolution to correct revegetation failures and estimate aboveground biomass and carbon.
