Beneficiation of Indian High Alumina Iron Ore Fines a Case

Two conceptual flow sheets have considered for the beneficiation of Indian high alumina iron ore fines. The first option, consisting of hindered settling classifier followed by two stage gravity concentration results in a product quality with 66.82%Fe and 2.1%Al 2 O 3 content ensuring 25.15% iron recovery.

An overview of the beneficiation of iron ores via reverse

Flotation is the most effective solution, both technologically and economically, when upgrading iron concentrates. Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores.
