DR-Grade Iron Ore Pellets - A Supply Overview - Midrex ...

Although direct reduction processes can operate with pellets having an iron content of 65% or lower, typical of blast furnace (BF)-grade pellets, the preferred feed for a DR plant has an iron content of 67% or greater. The principal sources of DR-grade pellets are located in South America, Canada, Sweden, Bahrain and Iran (TABLE I).

Iron Ore Pellet - an overview ScienceDirect Topics

Shaft furnaces use pellets (produced in the same way as pellets for the BF), or lump ore. Raw material for pellets is produced by crushing and grinding low-grade iron ores—typically of the taconite class and finer than 325 mesh (0.044 mm)—and magnetically separating the iron oxide (magnetite, Fe 3 O 4 ) from the siliceous gangue.
