What is iron ore pelletizing?

Pelletizing of iron ore Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets.

How are iron ore pellets produced?

Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. Designed and supplied the largest straight grate systems in the world.

What is iron ore concentrate?

Iron ore concentrate is produced from the magnetite iron ore in the beneficiation process and is used for the production of pellets for blast furnaces and sinter. The concentrates are non-toxic, non-flammable and non-explosive.

What is beneficiation of iron ore?

Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit.

What happens to the iron ore pelletizing process?

However, the content of iron in ore deposits has deteriorated and low-grade 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 with a special focus on binders. Bentonite is the

Why are iron ore pellets important to developing countries?

Iron ore and iron ore pellets are important sources of iron for manufacturing steel. The iron ore developing countries, such as China and India. However, the content of iron ore in deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the izing plant.

Can You induration iron ore with green pellets?

Studies of green pellets and induration of magnetite and high grade hematite iron ore fines with low alumina have been carried out in different parts of the world. But the results of these studies cannot be directly interpreted to iron ores with higher amount of alumina (Al2O3) due to the difference in chemistry and mineralogy.
