Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.

Traditionally the name 'Peacock Ore' was used to describe bornite, named for the classic iridescent sheen. Commercially for many years 'Peacock Ore' has been 'faked' by treating chalcopyrite with acid to produce a thin oxidized layer that has similar iridescent appearance to bornite. The iridescence on both these minerals, and other sulphides, is probably due …
