Ore Processing Of Low Grade Hematite

Hematite Processing by Flotation

Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.
