“…However, to develop applications for Fundão tailings, it is essential to characterize them thoroughly. Characterization studies were carried out shortly after the accident (Segura et al 2016;Almeida et al 2018;Queiroz et al 2018;Machado et al 2019). However, considering the material has been in the environment for years, new results must be obtained.…”

In this work, samples of Fe mining tailings from the collapsed Fundão Dam, Brazil, which were retained by the Candonga hydroelectric power plant, were characterized by various techniques. Quartz, hematite, kaolinite, and goethite were identified as the main phases present. The composition, homogeneity, and relatively low (~1%) organic matter content indicate potential for usage of these tailings in civil constructions. The next step of this work is to investigate such applications. If their feasibility is confirmed, the goal is to use this material for construction in the areas affected by the Fundão Dam rupture. This use will lead to positive socio‐environmental impacts in these regions, where tailings still need to be removed and damaged infrastructure needs to be repaired.
