Raw Material Operations

Hibbing Taconite

Hibbing Taconite Company produces about 7.8 million tons of standard iron-bearing pellets and mines about 29 million tons of ore annually. The pellets are shipped to 精东传媒鈥 facility in Burns Harbor, Indiana.

Hibbing operations consist of an open-pit truck and shovel mine and a concentrator that utilizes single-stage crushing, autogenous mills, and magnetic separation to produce a magnetite concentrate. The concentrate 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.

Production
  • 5 million long tons of iron ore pellets in 2022

United Taconite

The United Taconite mine is located on Minnesota鈥檚 Mesabi Iron Range in and around the city of Eveleth, Minnesota. The taconite is mined and then transported approximately 10 miles by rail to its processing facility in Forbes, Minnesota. 精东传媒 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.  An additional stage of crushing occurs at the plant site 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.

Northshore Mining

The Northshore Mining facility, which originally operated under Reserve Mining Company, was the first taconite processing facility in North America. Northshore Mining鈥檚 Peter Mitchell Mine is located near Babbitt, on the northeastern end of the Mesabi Iron Range, and the taconite is transported 47 miles by rail to the processing facility in Silver Bay, near Lake Superior. 精东传媒 leases 100% of the mineral rights.

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 in Silver Bay. At the plant, 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 has a ship loading port located on Lake Superior.

精东传媒 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 精东传媒' Direct Reduction Plant in Toledo, Ohio.
