Non-magnetic physical separation of hematitic/goethitic iron ore
In the Australian iron ore industry, different physical separation processes are employed to beneficiate hematitic iron ores. At Fortescue's Chichester operations, desanding circuits ( Clout, 2013) have been used to beneficiate −1 mm iron ore of around 54–57% Fe with significant reductions in SiO2 and Al2O3.
