Cleveland-Cliffs Inc

Cleveland-Cliffs owns or co-owns five operating iron ore mines in Michigan and Minnesota, as well as one indefinitely idled mine in Michigan.  We produce various grades of iron ore pellets, including standard, fluxed and DR-grade, generally for use in blast furnaces around the Great Lakes as part of the steelmaking process.

Hibbing Taconite

Hibbing Taconite (HTC) began production in 1976 and made its initial shipment in January of 1977. HTC is ISO certified in Quality and Environmental Management Systems and is a joint venture owned by Cleveland-Cliffs (85.3%) and US Steel (14.7%). It has an annual rated capacity of 8.0 million gross tons a year.

Hibbing operations consist of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, autogenous (AG) mills and magnetic separation to produce a magnetite concentrate, which is then delivered to an on-site pellet plant. From the site, pellets are transported by BNSF rail to a ship loading port at Superior, Wisconsin.

United Taconite

United Taconite (UTAC) Mine is located in Eveleth, Minnesota. 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 December 2003. In 2008, Cliffs acquired ownership interest to wholly own and operate United Taconite. It has an annual rated capacity of 5.4 million gross tons a year.

United Taconite operations consist of an open pit truck and shovel mine where two stages of crushing occur before the ore is transported by rail, to the plant site. At the plant site, the additional stage of crushing occurs before the ore is sent to the concentrator. The concentrator utilizes rod mills and magnetic separation to produce a magnetite concentrate, which is delivered to the pellet plant. From the site, pellets are transported by rail to a ship loading port at Duluth, Minnesota.

In 2017, Cliffs completed a $75 million capital investment project for operational upgrades and new infrastructure to produce a newly developed Mustang superflux iron ore pellet.

Northshore Mining

Northshore Mining (NSM), which originally operated as Reserve Mining Company, was the first taconite processing facility in North America when it opened in 1956. It was purchased by Cyprus Minerals in 1989, and Cleveland-Cliffs became the sole owner of the property in 1994. Northshore Mining’s Peter Mitchell Mine is located in Babbitt and the taconite is transported 47 miles by rail to the processing facility in Silver Bay, near Lake Superior. It has an annual rated capacity of 6.0 million gross tons a year.

Northshore operations consist of an open pit truck and shovel mine where two stages of crushing occur before the ore is transported along a wholly owned rail line to the plant site in Silver Bay. At the plant site, two additional stages of crushing occur before the ore is sent to the concentrator. The concentrator utilizes rod mills and magnetic separation to produce a magnetite concentrate, which is delivered to the pellet plant located on-site. The plant site has its own ship loading port located on Lake Superior.

Cliffs recently completed a $100 million expansion at its Northshore Mining operation to support large-scale commercial production of DR-grade pellets. With its completion, Northshore Mining is now the only U.S. based iron ore processing facility to produce low silica DR-grade pellets. The Northshore operation is producing DR-grade pellet feedstock inventory for Cliffs’ Hot Briquetted Iron Plant in Toledo, Ohio.

Minorca Mine

The Minorca taconite plant was constructed and operated by Inland Steel from 1977 until 1998 when it was purchased by then ISPAT International, a predecessor company of ArcelorMittal. Cleveland-Cliffs purchased Minorca Mine in 2020.

Minorca is located north of the town of Virginia in the northeast of Minnesota, which are accessible by road and rail. The processing operations consist of a crushing facility, a three-line concentration facility and a single-line straight grate pelletizing plant. Pellets are transported by rail to ports on Lake Superior. Lake vessels are used to transport the pellets to Indiana Harbor located in East Chicago, Indiana. Minorca supplies about 50 percent of No. 7 blast furnace’s pelletized iron requirements.

Tilden Mine

Tilden Mine is located in Michigan’s Upper Peninsula approximately five miles south of Ishpeming. Cleveland-Cliffs became sole owner of the mine in 2017. It has an annual rated capacity of 8.0 million gross tons a year.

Tilden’s operations consist of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, autogenous (AG) mills, magnetite separation and floatation to produce hematite and magnetite concentrates that are then supplied to the on-site pellet plant. Pellets are transported by LS&I rail to port at Marquette.

Tilden Mine operates an Environmental Management System in compliance with ISO 14011:2015 requirements.

Empire Mine

Empire Mine is located on the Marquette Iron Range in Michigan's Upper Peninsula, approximately 15 miles southwest of Marquette, Michigan. The Empire Mine has had no production since its indefinite idle began in 2016.

Prior to the indefinite idle, operations consisted of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, AG mills, magnetite separation and floatation to produce hematite and magnetite concentrates that are then supplied to the on-site pellet plant. From the site, pellets were transported by rail to a ship loading port at Escanaba, Michigan.
