10.1. Physical processing for enhanced chemical and/or physical properties. Hematitic/goethitic iron ore as a bulk commodity is normally treated at its source (mine) through relatively simple physical ore dressing processes of comparatively large scale to turn it into salable products prior to transportation. The overall purpose of such treatment …

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
