Converting iron ore into pellets is an important process that is carried out to prepare iron ore for use in blast furnaces.
:Methods of converting iron ore into pellets
1- Wet Balling Method:
In this method, iron ore powder is mixed with water and additives (such as adhesives) and formed into small balls. Advantages This method can lead to the production of uniform and high-quality pellets.
2- Dry Balling Method:
In this method, iron ore powder is pressed dry into balls without adding water. Advantages This method helps save water consumption and reduce production time.
3- Thermal Indurating Method:
After the pellets are produced, they are placed in special thermal furnaces to be baked and gain more strength. Advantages This step helps to improve the strength and quality of the pellets.
4- Mixer and pelletizer method:
In this method, powdered iron ore is mixed with binders and water in a mixer, then pellets are produced using pelletizing machinery. Advantages This method is usually used on a large and industrial scale.
5- Pelletizing method using a rotary kiln:
In this method, iron ore is heated with additives in a rotary kiln to become pellets. Advantages This method can enable the production of high-quality pellets.
6- Fluidized bed pelletizing:
In this method, iron ore particles are placed in a fluidized bed and pelletizing is carried out under the influence of air or gas flow. Advantages This method can help optimize energy consumption and improve the quality of pellets.
Each of these methods has its own advantages and disadvantages, and the selection of the appropriate method depends on the type of iron ore, production needs, and market conditions.
Wet balling and mixer-pelletizer methods are among the most common and widely used methods for converting iron ore into pellets.
These methods are of great interest in various industries, especially steel production, due to their optimization in energy consumption, high quality of the final product, and reduction of pollution. The selection of the appropriate method usually depends on the type of iron ore, production capacity, and specific needs of the plant.

?Which method is the least expensive to convert iron ore into pellets
Among the various pelletizing methods, dry balling is usually the least expensive. The reasons for this are as follows:
1. No water requirement: Dry balling requires less water and additives, which reduces the costs of water supply and treatment.
2. Reduced energy costs: This method is usually operated at lower temperatures and can consume less energy.
3. Simplicity of the process: The production process in this method is usually simpler and requires less equipment, which can reduce initial investment costs.
4. Reduced transportation costs: Since the pellets produced are usually of more uniform and convenient sizes, transportation and storage costs may be reduced.
However, it is important to remember that each method has its own advantages and disadvantages, and costs can be affected by factors such as market conditions, iron ore type and production needs. Therefore, the selection of the best method must be made with each plant’s specific circumstances in mind.
Iron ore to pellet conversion rate
The conversion rate of pellets to iron ore is not precisely known, because iron pellets are produced from iron ore powder, and the conversion ratio depends on various factors such as the type of iron ore, the pellet production process, and operating conditions.
But in general, in the pelletizing process, about 1.2 to 1.4 tons of iron ore are usually needed to produce one ton of pellets. This ratio may change due to the presence of moisture, additives, and other factors.
In general, pelletizing helps to increase quality and reduce pollution in the steel production process, and the conversion ratio is also one of the important points in optimizing this process.
The price per kilo of sponge iron depends on several factors, including the following:
Exchange rate: If sponge iron producers export, exchange rate fluctuations can affect prices
Transportation costs: The costs associated with transporting and distributing the final product to the market also affect the price
Energy costs: Energy costs, especially in the production process, including electricity and fuel, can affect the price of sponge iron
Market competition: The presence of multiple manufacturers and the level of competition in the market can also help determine price
Raw material prices: The cost of iron ore, coke, and other materials required to produce sponge iron has a great impact on the final price
Product quality: The quality of the sponge iron, which includes its purity and physical properties, can affect the price. Higher quality products usually command a higher price
Supply and demand: Changes in the supply and demand of sponge iron in the market can also affect the price. For example, increased demand in steelmaking industry increase the price
As a result, the price per kilo of sponge iron is a complex function of these factors and may change over time. To buy iron pellets and get detailed information on iron pellet prices, refer to the links provided.
Conclusion
Iron ore pelletization is a key process in the steelmaking industry that helps improve the quality and efficiency of steel production. In this process, iron ore is powdered and then converted into small, round iron pellets using various methods such as wet or dry pelletization. These pellets are effectively melted in blast furnaces due to their uniform size and suitable physical properties.
As a result, iron ore pelletization is not only essential for steel production, but also helps optimize energy consumption and reduce environmental impacts.
