AbstractThe present work aims to evaluate the feasibility of iron ore tailings from tailing dams as an alternative material for road infrastructure. The iron ore tailings were characterized according to their chemical, mineralogical, environmental, and physical properties. Subsequently, the tailings were chemically stabilized using cement, lime, or …

The size analysis and size fractional chemical analysis of the tailings are presented in Table – 1. It is apparent that about 80% of the tailings are less than 60 microns. The experiments were conducted with an objective to study the feasibility of producing filtered tailings amenable for dry stacking.

The drawbacks associated to the conventional tailings slurry disposal in dams can be managed by stacking filtered tailings in piles. In this regard, the addition of small amounts of cement into the tailings preceding the stacking may strengthen the engineering properties of the material, permitting the construction of higher and more …

An alternative and safer method regarding tailings disposal is the dry stacking of filtered tailings. Dry stacking stands for stacking compacted filtered iron ore tailings, which will allow tailings disposal sites (Consoli et al. 2022). Thus, enhance the understanding of tailings' behaviour is mandatory for safer design and construction of ...
