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.

在这项工作中，巴西 Fundão 大坝溃坝时被坎东加水电站截留的 Fe 矿尾矿样本，通过各种技术进行了特征描述。鉴定出的主要物相为石英、赤铁矿、高岭石和针铁矿。其组成、均一性和相对较低（约 1%）的有机物含量表明这些尾矿有用于民用建筑的潜力。这项工作的下一步是研究这些应用。如果确认其可行性，目标是将该材料用于 Fundão 大坝溃坝影响的地区的建筑。这种利用将对这些地区产生积极的社会环境影响，在这些地区仍需要清除尾矿并修复受损的基础设施。综合环境评估与管理 2020；16：636-642。© 2019 SETAC。
