Depending on the ore type, quality and its degree of degradation, a washing and classifying plant can increase the iron content by two to five per cent, while reducing the silica, alumina, titanium oxide, sulfur and phosphorous content through removal of fines below 0.063 mm by washing. For example, decreasing the alumina content reduces the ...

Indian iron ores are suffering from high amounts of alumina and loss on ignition (LOI), which are deleterious constituents in both the pelletizing as well as iron making processes. Iron ore fines utilized in pellet making consist of alumina in the range of 3.20–3.35% and LOI in the range of 3.50–3.70%. Detailed palletization studies have …

The iron ore fines were ground to below 150 μm using a laboratory ball mill (2 ft. x 2 ft) in closed circuit grinding. The particle size distribution of ground iron ore fine and slime samples were carried out by wet process using standard sieves (Table 1). It is observed that 95% of the slime particles are below 45 μm.
