Smelting reduction of iron ore-coal composite pellets has been carried out in an induction furnace. The pellets, tied with tungsten wire, were immersed into the liquid metal bath.
The best option is to convert the iron ore and coal/coke fines into cold bonded iron ore-coal composite pellets/briquettes. By producing composite pellets/briquettes from iron ore and coal/coke fines, utilization of these fines also takes place.
Three types of V-Ti (vanadium-titanium) iron concentrate powder were studied on their features as well as their influences on the properties of cold-bonded iron ore pellets. The research results indicated that the relations between the fineness modulus of the three types of V-Ti iron concentrate is in the order of LM>HL>SX, and SX has the smallest fineness modulus and particle sizes.

The sintering process is a continuous process which is based on treating a charge mix (ore fines, return fines, and fluxes etc.) layer in presence of coke breeze to the action of a burner placed in the surface ...
The feasibility of producing Direct Reduced Iron from cold-bonded self-reducing composite pellets made from Anglo American Kumba Iron Ore Sishen upgraded slimes was considered on laboratory scale. Composite pellets were made by mixing Sishen upgraded slimes, coke and different binders using a pelletizing disc by addition of moisture.

The reduction of iron ore-coal composite pellets was carried out in the temperature range of 500 ～1200°C by ... The fundamental reactions occurring during the heat treatment of cold bonded pellets (CBP) comprised of iron and steelmaking by-products have been studied [24]. .
Mandal and Sinha [7] concluded that (1) It has been possible to use fluxed iron ore pellets using iron ore and lime fines as a raw material to minimize flux input in Blast Furnace as a limestone ...
It utilizes iron ore micro-fines and coal fines or coke fines or carbon containing waste fines in iron making or sintering. The micro-pellets provide energy to the sinter bed for reduction in coke breeze consumption. 38-48 % reduction in coke breeze has been found when 38 % blast furnace flue dust containing pellets were mixed with iron ore in ...

By producing composite pellets/briquettes from iron ore and coal/ coke fines, utilization of these fines also takes place. Material Science & Engineering International Journal Research Article Open Access
Large amounts of fines and superfines are generated in Indian iron ore and coal mines due to mechanized mining and mineral dressing operations. Utilization of these fines for extracting metal is of vital concern for resource utilization and pollution control. For agglomeration of these fines, a suitable binder is required. Iron ore-coal composite pellets were prepared by cold bonding. Various ...
Feb 01, 1997· Reduction of the cost of the pellet and its gangue content require reduction of the amount of binder. This communication reports the results of an investigation on reduction of binder requirement in cold bonded pelletization of iron ore fines by using cement .

Of the 13.6 million tons of steel 7 million was exported, and 43.1 million tons of iron ore was exported at a value of $4.6 billion. Of the iron ore exported 38.5% of the volume was iron ore pellets with a value of $2.3 billion and 61.5% was iron ore concentrates with a value of $2.3 billion.
4.2 Physical properties of fired BPJ iron ore pellets 4.3 Physical properties of fired D.R Pattnaik Iron ore pellets 4.4 Degree of reduction and swelling values of fired BPJ haematite iron ore pellets reduced in Basundhara non-coking coal 4.5 Degree of reduction and swelling values of fired BPJ haematite iron ore pellets
The iron particulate materials, typically having a size range of from about 0.01 mm to 6 mm, include ore fines, sinter fines, BOF and EAF dusts, mill scale, and the like. Powdered carbonaceous material, such as ground coal or coke, may also be added to the pellets.
Cold-bonded composite pellets, consisting of iron ore fines and fines of noncoking coal or char, were prepared by steam curing at high pressure in an autoclave employing inorganic binders. Dry compressive strength ranged from 200 to 1000 N for different pellets. The pellets were heated from room temperature to 1273 K under flowing argon at two heating rates.
oxides) and coke as its raw materials. When pellets are used in a blast furnace, the iron burden material is charged in the form of pellets and fine, iron-rich by-products are charged typically in the form of cold-bonded briquettes at the top of the blast furnace. Coke is the primary fuel and reductant in .
