Fig 1 Flowsheet of sintering process. The iron ore fines are natural ore of size 0 mm to 10 mm. The raw mix (also called sinter mix) is made with the weighed amount of iron ore fines, limestone, dolomite, sand or quartzite fines (flux), solid fuel (coke breeze or anthracite) and metallurgical wastes (collected dusts, sludge and mill scale etc).
While iron ore is available in abundance, for coking coal, India remains heavily dependent on imports. Major players use only high grade ore (lumps), with 65 per cent and above iron content, to make steel through BF (blast furnace). Fines are low grade ore having iron content or 64 per cent or less.
It is an agglomerating process of converting iron ore fines into 'uniformed sized iron ore pellets' which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1.

The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted, by varying the pellet fines from 0 to 50% in the iron ore blend.
Rather, you need to heat the iron ore in an oxygen-deprived atmosphere in the presence of something else that will absorb the oxygen from the iron. Traditionally, carbon has been used for both the burning to produce heat and as the material that absorbs oxygen from the iron ore. ... Then grind your aluminum into a fine powder, and heat ...
Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the feed. Moreover, the excessive fines generated from the iron ore crushing units are mostly stored as waste. If we look at it, we find that the growth rate of steel industry has slowed down from 12.7% in 2009-10 to 4. ...

Fines: small screenings of ore (less than 6mm). Fines may be sintered to form large particles, lumps or masses by heating the material to below its melting point with another material (e.g. limestone or coke breeze) until its particles adhere together. ... This combines with the iron oxides in the iron ore to produce metallic iron known as pig ...
With this, the growing demand from countries, such as China and Japan for iron ore produced in countries, such as Australia and Brazil, is only increasing. Iron Ore Fines (IOF) are a product of iron ore, commonly having a particle size less than 6.3 mm, which is transported around the world in bulk carriers. Since the holds of bulk carriers are ...
PRODUCTION OF STEEL & IRON ORE REQUIRMENTS Crude steel production National Steel Policy announced in 2005 envisaged steel production of 65 MT in 2011-12 and ... - In addition, at the time of mining 60% of the ore comes as fines and balance 40% as lumps (including big boulders). Thus, in the total production of iron ore 70-72% are fines ...
Three possibilities of coal-based solid-state reduction of briquetted fine ore are discussed. The first one is still in laboratory scale and it employs production of self-reducing...
Code for Direct Reduced Iron Fines has been designated as Direct Reduced Iron (D) (By-product Fines with moisture content of at least 2%), abbreviated hereinafter to DRI (D). This schedule …
The case involved the classification of Iron Ore fines as Iron Ore lumps for export valuation and levy of export duty. The Tribunal held that the consignment, despite containing a certain percentage of Iron Ore lumps, should be treated as Iron Ore fines due to involuntary processes and the absence of deliberate mixing. The presence of Iron Ore ...
