The Mesabi Iron Range is a mining district and mountain range in northeastern Minnesota following an elongate trend containing large deposits of iron ore. It is the largest of four major iron ranges in the region collectively known as the Iron Range of Minnesota. First described in 1866, it is the chief iron ore mining district in the United ...
It is home to U.S. Steel's KeeTac taconite mining and processing plant. Kinney (pop. 169) is an old mining boomtown on the Iron Range, between Buhl and Mountain Iron. Mountain Iron (pop. 2,869) is home to Minntac, the world's largest taconite processing plant. Nashwauk (pop. 983) is a small town between Grand Rapids and Hibbing, 4 miles from ...

Edward Wilson Davis (May 8, 1888 – December 3, 1973) was an American engineer and inventor famous for pioneering early research into taconite.As a researcher at the University of Minnesota, Davis developed an engineering process to economically extract iron ore from hard taconite rocks, making taconite valuable as iron ore for the iron and steel industries.
The U.S. Environmental Protection Agency recently took steps to limit emissions from taconite mines. But proposals to build Minnesota's first sulfide-ore mine to extract copper and nickel near the ...
