Minnesota's state mineral is iron ore.
Minnesota
Minnesota gained statehood in 1858 it became the 32nd US state. The state was rich in iron ore.
Minnesota
The state "gem" in the Lake Superior Agate. I am not sure there is a "Sate mineral" though iron ore has played a major role in Minnesota's history and economy due to the Iron Range in the Northern part of the state.
There are many important industries in Minnesota, one industry is iron-ore mining. Minnesota supplies 70% of all the iron ore produced in the United States. If you drive an American car, it probably has steel in it that was made from Minnesota iron ore.
The top iron ore producing states in the United States are Minnesota, Michigan, and Utah. Minnesota is the largest producer, accounting for the majority of domestic iron ore production. Michigan and Utah also have significant iron ore mining operations.
The Mesabi Iron Range is in the Northeastern part of the state of Minnesota. Cities like Viriginia, and Hibbing are near the Iron Range. The Iron range is near Lake Superior and iron ore mined there is often shipped from Lake Superior port cities like Duluth over great lake water ways to steel plants.
