United Taconite mine in Eveleth, Minnesota
The mining process at United Taconite begins with the removal of overburden, which is the layer of rock and soil that covers the iron ore deposit. Once the overburden is removed, the iron ore is blasted and loaded into trucks. The trucks then transport the ore to a crusher, where it is broken into smaller pieces. The crushed ore is then transported by rail to the Fairlane Processing Facility in Forbes, Minnesota.
At the Fairlane Processing Facility, the crushed ore is further processed to remove impurities and concentrate the iron content. The concentrated ore is then formed into pellets, which are small, high-grade iron ore balls that are used as a feedstock in steelmaking.

Iron ore pellets at United Taconite are an important economic driver for the region. The mine employs approximately 500 people and generates millions of dollars in revenue each year. The mine also provides a source of raw materials for the steel industry, which is a vital part of the U.S. economy.The Highway 53 Bridge over Rochleau Pit in Virginia, Minnesota is the tallest bridge in the state, standing 204 feet above the water. It is a haunched girder bridge made of weathering steel, and it crosses a total distance of 1,125 feet. The bridge was completed in 2017 and replaced an older bridge that was no longer able to support the weight of modern traffic.

The bridge is located in the heart of the Iron Range, a region of Minnesota that is known for its iron ore mining. The Rochleau Pit was once an active iron mine, but it is now filled with water and serves as a drinking water source for the city of Virginia.

is a vital transportation link for the Iron Range. It carries traffic between Virginia and other cities to the south, and it provides access to the Mesabi Trail, a popular bike and pedestrian trail.
