A statistical randomised block design' full plant trial of magnetic conditioning of flotation feed was undertaken at Rio Tinto's Northparkes Mine in New South Wales. Magnetic conditioning of flotation feed has been shown to improve the flotation of 38 m paramagnetic minerals consistent with selectively aggregating these paramagnetic minerals.
