Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in consumer demands. Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores.
