taconite Definition, Uses, & Facts Britannica

taconite, a low-grade siliceous iron ore composed of 20–30 percent magnetite that occurs in fine-grained banded iron formations. Taconite is mined primarily in the U.S., in the Mesabi Iron Range in Minnesota and the Marquette Iron Range in Michigan. Recovery of the iron requires fine grinding and concentration of iron-bearing phases, which in turn are formed into pellets

Taconite is a low-grade iron ore. When the high-grade natural iron ore was plentiful, taconite was considered a waste rock and not used. But as the supply of high-grade natural ore decreased, industry began to view taconite as a resource. Dr. E.W.
