Charging the blast furnace/ BOS plant Pellets are primarily used in blast furnaces and are also used in DRplants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material)

This process of directly reducing the iron ore in solid form by reducing gases is called direct reduction. In this process coal will be used for producing reducer gas and
Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh ( mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium to highgrade (+62% Fe) and are directly used in blast furnace and in directreduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and SteelVision, 2020).
The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted ...

Pellet plant is facilitated with additives grinding unit as the process of pelletization requires binder and additives. Bentonite is used as a binder for proper balling of the filter ...
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...
Processes that produce iron by reduction of iron ore (in solid state) below the melting point are generally classified as DR processes. B a s e do nt h e types of reductant used, DR processes can
We are Turkey's first and only iron ore pelleting facility. We have a 34% share in the country's iron ore output and meet 12% of its demand for iron ore.

Iron Ore Pellet Plant Process Flow Chart. The flow charts always in the subjects help to understand better. The process in the iron ore pellet plant is the process through which the particles get larger so that they are used in the blast furnaces. They have to be big enough for the process. In agglomeration, the two methods are followed by the ...
Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to blast furnace is always preferred. Indian ...

The pellet plant has a 336 sq meter travelling grate indurating machine, designed to produce 6060 dry metric tons (DMT) of iron oxide pellets on daily basis.
Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.
The pelletization process for magnetite ores can be broadly categorized into three subprocesses raw material preparation, balling and induration, a schematic of process flow is shown in Figure 3 ...

A fullscale plant trial of the substitution of a specific organic binder for bentonite was conducted in the company's straight grate pellet plant in Quebec, which produces Mtpa of pellets, 36% of which are used as feedstock for the DR process. The results of the fullscale pellet plant trial are given in Table
For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.
Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.
The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from Mta capacity to 28 Mta in the forthcoming years.
Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and process is considered an excellent option for the storage and transport of said materials. The technology is widely used in the powder metallurgy engineering ...
