Iron ore slime generation in India is 15–20 % (by weight of the mined ore) (Manna et al., 2011), whereas 20–40 % of the mined ore in Brazil is off-grade fines/slimes (Matiolo et al., 2020). Despite the high Fe content (40–57 %), Indian iron ore slime finds no takers because of its high alumina and silica contents.
