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.

Fundão悲剧的尾矿：Candonga大坝保留的材料的物理化学性质。

在这项工作中，采用各种技术对巴西坍塌的Fundão大坝的Fe采矿尾矿样品进行了表征，这些样品由Candonga水力发电厂保留。石英，赤铁矿，高岭石和针铁矿被确定为存在的主要相。组成，均质性和相对较低（〜1％）的有机物含量表明在民用建筑中使用这些尾矿的潜力。这项工作的下一步是研究此类应用程序。如果证实了其可行性，则目标是在受Fundão大坝破裂影响的地区使用这种材料进行建筑。这种使用将在这些地区带来积极的社会环境影响，那里的尾矿仍需要清除，受损的基础设施也需要维修。整合环境评估管理2020; 16：636-642。©2019 SETAC
