How are iron ore pellets manufactured?
Iron Ore Pellets are formed from beneficiated or run of mine iron fines. The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent.
Who has the best iron ore?

Australia and Brazil are among the world’s largest iron ore producers and hold a large portion of the world’s iron ore reserves. Australia makes up half of the world’s iron ore exports. Brazil exported around 23 percent of the world’s total iron exports.
What is steel pellet industry?
What are pellets? Pellets are small balls of iron ore used in the production of steel. They are made with technology that uses the powder that is generated during the ore extraction process, once considered waste.
Does USA have iron ore?

What is iron ore beneficiation?
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.
Does China have its own iron ore?
As the largest country in terms of steel output and exports, China’s demand for iron ore has been strong. However, China depends heavily on iron ore imports, with around 80 percent of iron ore resources coming from abroad. About 60 percent of China’s iron ore resources come from Australia and 20 percent from Brazil.

What is the pelletizing process of iron ore?
Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. 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.
What is the difference between iron ore beneficiation and pellets plant?
Pellets plants are normally integrated with the iron ore beneficiation plants. In case they are not integrated then concentrated iron ore in slurry form is usually pumped to the pellet plant by slurry pipelines. Pellets plants based on rich iron ore fines are rare and not very economical.
What is the fired pellet strength?
The fired pellet strength is, to a certain degree, due to hematite bridges of polycrystalline structure. These pellets normally have large volume of open pores. The reduction gas quickly penetrates through these pores into the pellet core and simultaneously attacks the structure in many places.
What is the best method for the production of green pellets?
Pelletizing discs or balling drums are used for the production of green pellets. Pelletizing discs are more popular for the production of green pellets. Vibrating screens are normally used for separating different fractions of green pellets.
