iron ore 65 fe at beneficiation

What Is Iron Ore Beneficiation? (with pictures)

Iron ore is smelted after going through beneficiation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. High-grade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.

POTENTIAL APPLICATIONS FOR DRY BENEFICIATION OF IRON

As an example, for the typical ore tested with a two-pass flowsheet, an increase of 15% in iron grade (i.e. from 50% Fe to 65% Fe) would predict an iron recovery of 90%. Lower iron recoveries are voluntarily used in the following case studies in order to consider the inherent loss of recovery when producing higher grade iron ore concentrates.
