· In North America, the term taconite is used to describe magnetite- and hematite-rich BIF-GIF ore with > 30 wt% Fe (James, 1954, Neal, 2000). In Australia, Africa, and Brazil, little unenriched iron formation ore has been mined to date due to the presence of significant resources of direct-ship or easily beneficiated high-grade hematite and

Banded iron formations are locally known as taconite within North America. Mining and processing of banded iron formations involves coarse crushing and screening, followed by rough crushing and fine grinding to reduce the ore to the point where the crystallized magnetite and quartz are fine enough that the quartz is left behind when the resultant

Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away.

Taconite. The mines on the Mesabi Range historically extracted hematite, a rusty-red gravel-like ore. Hematite contained 50–70% iron and could be dug out of the ground and shipped right out to be made into steel. From 1890 to about 1980, 2.5 billion tons of this ore was mined here, but these “natural ores” were largely depleted by the 1980s.
