What type of ore is taconite?
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.
Where does taconite come from in Minnesota?
Taconite. Taconite is mined from the Mesabi Iron Range, near Hibbing, MN. Then it is processed into pellets and moved by train--or on ore boats from Duluth--to ports and steel mills around the Great Lakes region.
Who are the producers of taconite?
Major producers of iron ore pellets from taconite in North America include Iron Ore Company of Canada, Cliffs Natural Resources, Inc., U.S. Steel, and ArcelorMittal. These processed taconite-ore pellets are also referred to as "taconite".
Why do we need taconite?
As the supplies of high-grade ore dwindled in the years preceding World War II, alternative sources of iron (and for the Iron Range, new industries) were sought and our attention once again turned towards taconite.
What is taconite used for?
Taconite is mined from the Mesabi Iron Range in Northern Minnesota. It is a very hard rock containing low-grade iron ore used to make iron and steel. Using explosives, taconite is blasted into pieces that are then crushed into smaller pieces at a processing plant.
How much is a ton of taconite worth?
Lehtinen said the cost to produce traditional taconite is $60 to $80 per ton in Minnesota, with transportation to China about the same cost. "So, the price is still in that neighborhood of being profitable" to sell overseas, he said.
Who owns the taconite?
The Taconite's owner, Capt. Gordon Levett, listed her for sale for $2.5 million in 2015. Since then, Kristina Long, a Taconite admirer who has captained other classic boats, has been trying to find a local buyer to prevent losing a B.C. treasure.
How much iron is in a taconite pellet?
The magnetite is separated with magnets and agglomerated into marble-sized pellets. The finished pellets contain over 65% iron. These pellets are shipped to steel mills.
Where is the largest iron ore mine in the United States?
MinnesotaMinntac Mine The Minntac Mine is a surface mine located in Minnesota. It is owned by United States Steel and produced an estimated 12.791 MTPA of iron ore in 2020.
How much taconite is left in Minnesota?

Which state is the Center for iron and steel mining?
MinnesotaMinnesota. Minnesota provides the great bulk of the iron ore mined in the US. Iron ore comes from seven open-pit mines, and two tailings reclamation operations, one in St. Louis County, and one in Itasca County.
What Mines does Cleveland-Cliffs own?
Cleveland-Cliffs owns 100% of the United Taconite mine and leases 100% of the mineral rights. Operations consist of an open-pit truck and shovel mine, where ore is crushed in two stages before traveling by rail to the plant site.
Does Cleveland-Cliffs mine nickel?
Since then, Cleveland-Cliffs has strengthened its core U.S. iron ore business and sold its coal-, chromite- and nickel-mining assets. The company celebrated its 170th year in business in 2017 and chose a site in Toledo, Ohio, for its first hot briquetted iron production plant.
What ports is taconite currently shipped out of?
The taconite iron ore pellets are hauled by railroad to the ports of Silver Bay, Two Harbors and the Twin Ports of Duluth, Minnesota, and Superior, Wisconsin, all on Lake Superior.
What's the difference between iron ore and taconite?
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.
Are taconite pellets magnetic?
Taconite saved Minnesota's iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism.
What's the difference between iron ore and taconite?

Who invented taconite?
E. W. Davis of the University of Minnesota Mines Experiment Station is credited with developing the pelletizing process. Since the commercial development of this process in the Lake Superior region in the 1950s, the term "taconite" has been used globally to refer to iron ores amenable to upgrading by similar processes.
What percentage of iron is in taconite?
Taconite has a very low iron content — at best, only 32.5 percent of the rock is iron ore.
