Iron Ore Pelletizing Process: An Overview | …
10-07-2017 · 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 low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking.
Introduction to Iron ore Pellets and Pelletizing …
Process technology. There are four stages involved in the production of iron ore pellets. These stages consist of (i) raw material preparation, (ii) formation of green balls or pellets, (iii) induration of the pellets, and (iv) cooling, storage and transport of pellets.

Iron Ore Processing for the Blast Furnace
blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").
Iron ore pelletizing systems - liming
Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don’t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.

Pelletizing - Wikipedia
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 stone composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.

Iron Ore Pellets and Pelletization Process – IspatGuru
Iron Ore Pellets and Pelletization Process. 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.
