Iron Ore Agglomeration Processes and their Historical

28/12/2015· Iron Ore Agglomeration Processes and their Historical Development. There are four types of agglomerating processes which have been developed (Fig 1). They are (i) briquetting, (ii) nodulizing, (iii) sintering, and (iv) pelletizing. Fig 1 Agglomeration processes. Briquetting is the simplest and earliest applied process. Fine grained iron ores are pressed in to pillow shaped briquettes with the

A Detailed Look at Iron Ore Agglomeration

Pellets around 4-10 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The ‘recipe’ for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests

Iron ore, its beneficiation and agglomeration as

19/03/2008· E. Agglomeration of Iron Ore: Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the fee. So, they are agglomerated (by igniting at lower temperature causing only interfacial fusion) into larger lumpy pieces with/without addition of additives like limestone, dolomite etc.

FE Techno Engineering & Power Solutions Agglomeration

The principle of sintering involves the heating of iron ore fines along with flux and coke fines or coal to produce a semi-molten mass that solidifies into porous pieces of sinter with the size and strength characteristics necessary for feeding into the blast furnace. It is basically an agglomeration process achieved through combustion. The Product Sinter The product of the sintering process

EFFECT OF SIZE DISTRIBUTION AND WATER CONTENT ON

The major agglomeration processes for iron ore fines are pelletisation and sintering. The two processes complement each other as they utilise fines of different size ranges. Other lesser-known agglomeration processes include stamping, briquetting, etc. However, these processes have more or less been outdated due to the low efficiency and lack of economic viability. With the fast-growing pellet

Circored and Circofer processes of ironmaking IspatGuru

The special features of the process are (i) direct use of iron ore fines without prior agglomeration, such as pelletizing or sintering, and (ii) operation with pure hydrogen as reducing gas enables reduction with very low CO2 emission values, and allows the application of low reduction temperatures minimizing sticking tendencies. H2 is produced by means of natural gas reforming, but H2 from

Furthermore, in spite of being rich in iron content, Indian hematite ores have adverse Al 2 O 3 and SiO 2 ratio of 1.5-3.0 for lumps and 3-4 for fines. This adverse ratio is detrimental to both blast furnace and sinter plant productivity and should be less than

1.2 Agglomeration:-The fines that are produced in the mineral processing plants cannot be used directly in the blast furnace. These iron ore fines cannot be used directly in the blast furnace. They causes following threats:- 1. The fines decrease the bed permeability and hinder the bed reaction. 2. The fines leave the blast furnace with the flue gas, which brings down the blast furnace
