Recent reports suggest that aging is not solely a physiological process in living beings;instead, it should be considered a pathological process or disease(Amorim et al., 2022). Consequently, this process involves a wide range of factors, spanning from genetic to environmental factors, and even includes the gut microbiome(gM)(Mayer et al., 2022). All these processes coincide at some point in the inflammatory process, oxidative stress, and apoptosis, at different degrees in various organs and systems that constitute a living organism(Mayer et al., 2022;AguilarHernández et al., 2023).

Technical Proposal for the Recovery of Iron Tailings in Dams in the Context of a Circular Economy

引用

Journal of geoscience and Environment Protection 2025年第1期13卷 387-396页

作者： vidal Félix Navarro Torres geraldo Aparecido do Vale Eduardo da Rosa Aquino Instituto Tecnolgico Vale-Minerao Ouro Preto Brazil Vale S.A. Parauapebas Brazil

The objective of this study is to present a tailings recovery project in a dam located in northern Brazil;the tailings in this dam have high concentrations of iron. The sustainable recovery of mineral resources can be achieved using the dredging method. The methodology used was based on two drilling projects conducted in 2001 and 2010;these projects contained samples with information on the chemical composition and particle size fractions. The dredging system was designed to operate with four cutter suction dredgers. For operation, factors such as productivity, pumping distance and material flow were considered. The material contained in the dam was estimated using the natural neighborhood interpolation method;this resulted in approximately 192 million tons of tailings, with an average iron content of 63.37%. Based on these data, a 13-year mining plan was prepared, with the potential to maximize the use of the tailings and reduce the environmental impacts, thus contributing to a circular economy.
