Performance analysis for filtered iron ore tailings disposal. The generation of tailings is an inevitable concern of mining operations, since they are generated in large quantities and affect the environment both qualitatively and quantitatively. Rarely are minerals found pure in nature; generally they are found in small concentrations in raw ore,
30/9/2020 The annual disposal of iron ore tailings in Brazil is about 200 million tons, approximately 35% of the total generation of tailings in the country (IPEA, 2012). In addition to this large volume of
are numerous challenges to understand and manage these structures in regions of high rainfall and high disposal rates. In this context, the objective of this article is to evaluate the liquefaction susceptibility of filtered iron ore tailings, based on field
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.
1/10/2016 Trends in use of dewatered tailings in mining: filtered tailings disposal represents approximately 35% of the method utilized in tailings facilities . Although projects have demonstrated the technical feasibility of iron ore tailings filtering ,it has not been yet implemented in iron ore
