Minnesota produces 70 of this mineral in the us. The report said Minnesota was the fifth largest producer of mineral value in the nation including taconite iron ore but also sand gravel and stone totaling 327 billion. Nevada was the top. Minnesota is the largest US.
Producer of taconite an ore of iron. Coal is also mined there. Sand of sufficient quality for glass making is produced there.
And a high grade clay called kaolin is. Just under one-half of the sand and gravel went to concrete aggregates with the rest going to other construction uses like road base and stabilization asphalt concrete and construction fill. Texas California Michigan Minnesota Utah.
If you have ever been to the Smithsonian Museums mineral section you probably saw a stromatolite from Minnesota. Here is a web page that describes some collecting of this mineral along with many others. It has old info 2000 but still is interesting.

Who ownsand who benefits fromMinnesotas minerals. The DNR estimates that about 70 of Minnesotas mineral rights are privately held primarily in the southern two-thirds of the state where surface and mineral estates are less often severed. Among the private owners mining companies own hundreds of thousands of acres.
Large trusts and family estates with ownership dating back to the earliest prospectors and investors own thousands more. Some companies buy or lease mineral. US iron ore mining is dominated by the Precambrian banded iron formation deposits around Lake Superior in Minnesota and Michigan.
Such deposits were also formerly mined in Wisconsin. For the past 50 years more than 90 percent of US iron ore production has been mined from the Lake Superior deposits. None of the iron ore now mined in the US is direct shipping ore ready to be fed into the.

The first lease for mineral exploration at Hill Annex came shortly thereafter in 1892.
It took another decade for actual mining to begin but when it began it began in a big way. Hundreds of mines have operated on Minnesotas Iron Range. Hill Annex was one of the most productive of them.
Over the mines life it produced 63 million tons of iron ore making it the states sixth largest producer. Northeastern Minnesota is a region prized not only for its economically important taconite mining industry but also for its many wetlands and fishing lakes. Thus the Minnesota Department of Natural Resources has undertaken this two-year study on mercury cycling and distribution in northeastern Minnesota with emphasis on taconite processing.
The overall goal of this study is to provide a. Although there has been some nonferrous mineral exploration in Minnesota in the 1960s to 1980s a number of factors have come together to bring the Duluth Complex to the forefront of nonferrous deposits to be developed. Increasing population helping increase demand the ongoing depletion of known and developed world resources and the advancement of technology in using a cleaner safer process to extract minerals.
