The use of conventional bentonite binder is favorable in terms of mechanical and metallurgical pellet properties, however, because of its acid constituents bentonite is considered as impurity especially for iron ores with high acidic content.

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. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...

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. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets. This mixture is blended together ...

Iron Ore Pelletizing Bentonite. The need for iron ore pellets is directly connected to the steel production industry. Through the pelletizing process, iron ore fines are converted into spherical pellets, which are then suitable as feed material in blast furnaces for pig iron production.

However, bentonite is aluminium silicate clay and therefore the use of it is a contradiction since the purpose of iron ore preparation for pelletizing is the removal of those since they are ...

The use of conventional bentonite binder is favorable in terms of mechanical and metallurgical pellet properties, however, because of its acid constituents bentonite is considered as impurity especially for iron ores with high acidic content. Therefore, alternative binders to bentonite have been tested. Organic binders are the most studied binders and they yield pellets with good wet strength ...

Bentonite Market size crossed USD 1.1 billion in 2017 and industry expects consumption of more than 25 million tons by 2024, driven by rising demand from iron pelletizing market owing to booming infrastructure and automotive sectors in APAC region.

Hence, the suggested combined binders can be used as binder in place of bentonite in iron ore pelletizing without compromising the pellet chemistry. Discover the world's research.

The ratio in the output from the three main pelletizing technologies changes depending on practical circumstances, such as iron ore reserves, iron ore types, market demand, and required investment. The ratio for grate-kiln pellets has increased to 55.33% in 2011 from 7.21% in 2000, while the ratio for shaft furnace pellets has dropped to 42.05% ...
