Sep 25, 2018· These techniques are used in various combinations for the beneficiation of iron ores. Iron ore is normally beneficiated utilizing the principles applied in separation of the materials by the gravity, floatation, and magnetic methods. Enrichment of ores utilizing the gravity concentration method is one of the oldest and most economic techniques.

However, if the analysis is normalized to correct for loss on ignition (crystal-bound water) from goethite during sintering or pelletizing, the calcined fine ore values for traded iron ores and concentrates vary within a remarkably narrow range of 4.3–10.5% for (SiO 2 + Al 2 O 3) and 61.8–66.3% for Fe. Table 2.8.
