 · Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a high-quality product. Sintering and pelletizing are economic and widely used agglomeration processes to prepare iron ore fines/iron concentrate for ironmaking use.

Even if all of the iron appeared as magnetite, no more than about 34.5 to 48.4 percent of the ore would consist of magnetite. The Iron Bridge magnetite mine is expected to …
