What is mined from the Mesabi mountain range?
iron ore
The Mesabi Iron Range is in northern Minnesota. It is bordered by the Superior National Forest to the north, and is a 65-mile swath of land that is rich in iron ore. In fact, iron ore has been mined here for over 125 years!
What system of mining was used in the Mesabi Iron Range?
There were three methods of mining natural iron ore used on the Mesabi Range: open pit, underground, and milling. One to all three methods could be utilized at a given mine. Often a mine would start out as an underground operation and later become open pit.
Does the Mesabi Range still produce iron ore?
In the past, iron ore was mined on three iron ranges – the Cuyuna, Mesabi and Vermilion – and also in Fillmore County in southeastern Minnesota. Today, only the Mesabi Range still has iron ore/taconite mining taking place. Clay is mined in the Minnesota River Valley.
Which states contains the Mesabi Range?
northern Minnesota
Mesabi Range, largest of three iron ranges in northern Minnesota, U.S. (the others are Vermilion and Cuyuna).
Where can I find gold in Minnesota?
As per Minnesota Department of Natural Resource(MDNR), they have discovered six major areas which has gold deposits. These sublimates are found in Bigfork, Cook, International Falls, Linden Grove, Vermilion, and Virginia Horn.
How was mining on the Vermilion Iron Range different from the Mesabi Iron Range?
The Vermilion, along with the Mesabi and Cuyuna Ranges, constitute the Iron Ranges of northern Minnesota. While the Mesabi Range had iron ore close enough to the surface to enable pit mining, mines on the Vermilion and Cuyuna ranges tended to be deep underground. The Soudan mine was nearly half a mile underground.
How was the Mesabi Range formed?
Most of the world’s iron ore, including that contained in northern Minnesota, was formed during the middle Precambrian. During this period, erosion leveled mountains. This erosion released iron and silica into the waters of a new sea. Marine algae living in this new sea raised the level of atmospheric oxygen.
Is there Silver in Minnesota?
Minnesota has excellent mineral potential. Much of Minnesota’s geologic terrane is a continuation of the mineral-rich Canadian Shield of Ontario and Quebec, which has yielded gold, silver, zinc, copper, nickel, titanium, and other precious metals and base metals.

What is the Mesabi Iron Range?
The Mesabi Iron Range is an elongate trend containing large deposits of iron ore, and the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota. Discovered in 1866, it is the chief iron ore mining district in the United States. The district is located in northeast Minnesota,…
When was the first mine on the Mesabi Range?
This area of the Mesabi Range was explored in 1893–1894, shortly after the Mountain Iron Mine was established in 1892. The early development was as an underground mine, but open cast mining soon proved to be a better choice because of the soft, shallow ore deposits.
What cities are near Mesabi MN?
Nearby towns include Grand Rapids, Hibbing and Virginia, Minnesota. The Mesabi Iron Range is an elongate trend containing large deposits of iron ore, and the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota.
What caused the formation of the Mesabi Iron Range?
Marine algae living in this new sea raised the level of atmospheric oxygen, causing the eroded iron to precipitate into the iron formations now found in the Mesabi Iron Range. The Hull-Rust-Mahoning Mine in Hibbing, Minnesota, is the largest open pit iron mine in the world.
