Abstract

In this work, samples of iron mining tailings from the collapsed Fundão Dam, 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 organic matter content, ca. 1%, indicate potential for usage of these tailings in civil constructions. The next step of this work is to investigate such applications. If the feasibility is confirmed, the goal is to use this material for constructions in the areas affected by the Fundão Dam rupture. This will lead to socio-environmental positive impacts in these regions, which still need the removal of the tailings and repairs in damaged infrastructure. This article is protected by copyright.
