The Reserve Mining Company discharged taconite tailings directly into Lake Superior for 25 years, creating a massive tailings delta and polluting the waters of the lake. When the EPA took Reserve to court in 1973, the town of Silver Bay was divided between a struggle for economic well-being and public health.

Today, mine operators in Michigan's Upper Peninsula are generally after taconite, a low-grade ore that was once considered waste rock. To make it usable, mining companies blast it into small pieces with explosives, grind it into powder with powerful machinery, and then use magnets or flotation techniques to separate the iron minerals out from ...

United Taconite (UTAC) Mine is located in Eveleth, MN. The taconite is mined and then transported approximately 10 miles by rail to its processing facility in Forbes, MN. The mine began operating in 1965 as EVTAC Mining Company until 2003. Subsequently, Cleveland-Cliffs and Laiwu Steel Group jointly purchased the mine assets in Dec. 2003.

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. Davis of the University of Minnesota, along with other scientists and engineers, conducted years ...
