 — The capacity increased from 20.70 in 2010 to 37.4 Mt/year. This has been necessitated by a drop in iron ore production through bans on production as a result of illegal mining detected in iron ore-producing states like Karnataka and Goa and imposed caps on production on well-known iron ore-producing belts of Orissa.

 — Russia's hot-briquetted iron and direct-reduced iron capacity is set to more than double over the next five years to over 17 million mt/year, according to projects in the pipeline, meaning the country's production or procurement of DR-grade pellets needed to feed new HBI and DRI furnaces will also have to double.

 — The Brazilian miner plans to expand the capacity of its Malaysian iron ore distribution and blending center by 10 million mt/year to 40 million mt/year in 2022, to allow for more blending and sales into new markets. The $130 million expansion will allow the hub to tap new customers in India and Southeast Asia, Vale said.

 — In January 2023, the Company announced the positive findings of a study evaluating the upgrade of half of the Bloom Lake mine capacity to a direct reduction quality pellet feed iron ore and approved an initial budget to advance the project. Bloom Lake's high-grade and low contaminant iron ore products have attracted a premium to the Platts ...

 — The results show the approximately linear increase in specific energy in the operation as specific force increases. The slope of the linear relationship gives an idea of the deformability and energy absorption capacity of the feed material (iron ore concentrate).

 — It was installed at Empire Mines in 1963 which had six individual concentrating lines having a combined capacity of 1.6 Mtpa of iron ore pellets. There have been three expansions since, and in the 1990s Empire Mines had a total of 24 individual concentrating lines and a total plant capacity of 8 Mtpa of iron ore pellets.

 — 2.2 The Iron Ore Challenge. The world's iron ore resources are characterized by association with non-Fe gangue materials (silica SiO 2, alumina Al 2 O 3). While it would be ideal to 'beneficiate' the iron ores and get rid of the gangue before its use in the high temperature processes—most ores respond only to a degree.

 — Iron ore pellets are a better feed for iron and steel making as compared to other feeds. ... Bahrain Steel will more than double its iron ore and pellet storage capacity from 1.8 million tons to 4 ...

 — For pelletization study, as received iron oxide pellet fines were ground to below 150 μ using ball mill. The particle size distribution of ground iron ore fines was determined by the Malvern particle size analyzer (Hydro 2000MU, UK) and shown in Fig. 2.Blaine number was measured to determine surface area of the iron oxide pellet fines …

 — Brazil's Vale expects to increase its iron ore pellets production slightly in 2021 following 2020's plunge and to ramp back up to its previous production levels of between 50 million and 60 million mt ... "The main restriction is production of pellet feed," Spinelli said, noting the company is still under capacity at various mines in its south ...
