Iron ore tailings generated during beneficiation process of low grade iron ore fines from Rungta mines, Barbil, Odisha, India were used for the present studies. The slurry density of tailings received for dewatering studies was 1125–1200 kg m −3 and the particle density was around 3500–3600 kg m −3 .

Iron ore tailings (IOTs) are an inevitable by-product produced during the beneficiation process of iron ore (Almeida et al., 2023). The rapid growth of mineral mining and ferrous metallurgy has led to an increase in the generation of IOTs. Approximately 0.40–0.60 tons of IOTs are generated in the treatment of 1.0 ton of iron ore.
