Minnesota Iron Iron Mining History

The story of iron, in Minnesota, began over one and onehalf billion years ago when a vast, shallow sea covered the northern part of the state we know today. The Mesabi Range began in this sea, which contained concentrations of iron and silica. The iron and silica settled to the bottom of the sea and

Environmental impact of iron ore mining

Mining and processing. Common methods of extracting the iron ore consist of blasting, drilling, or general excavating,,. Most iron ore is produced from openpit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant.

THE IRON RANGES OF MINNESOTA

Several taconite mines and processing facilities are currently operating on the Mesabi Range. It has long been the goal of Mesabi miners to produce a pure iron product in northern Minnesota. In 2010 a new plant began production of 97% iron nuggets. The nuggets, along with iron and steel scrap, are used in electric arc steelmaking furnaces.

produced from Minnesotas Mesabi Iron Range iron ore. Modern Taconite Production. Iron ore is both mined and upgraded on Minnesotas Mesabi Iron Range. After being extracted from the ground, low grade iron ore is hauled from openpit mines to nearby taconite processing facilities, where it is crushed into a fine powder.

Taconite Minnesota DNR

Dr. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the taconite rock. After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry.
