Beneficiation of iron ore with high alumina

Beneficiation of iron ore with high alumina

Iron ore fines which get generated during mining are soft and rich in alumina with high amount of ultra fines. These characteristics of iron ore fines make it difficult to produce good grade pellets for use in COREX iron making units. Apart from this, high alumina in the pellets increases the
