The quality requirement of iron ore concentrate for steel production in India is mainly governed by silica and alumina. Apart from silica and alumina other minor deleterious impurities such as sulphur, phosphorous, arsenic, zinc, lead and other metals are to be also considered. The Al2O3 / SiO2 ratio should be less than one for blast furnace feed. The quality specification of ore for iron making …beneficiation plants for upgrading iron ore and pelletizing plants for agglomerating. The iron ore fines cannot be directly used in the blast furnace as they severely reduce the permeability of the blast furnace bed and bring down the efficiency of the furnace. To overcome this, agglomeration of high grade iron ore fines is done to serve as blastاقرأ أكثر
