MN mining has a long history, beginning with the native peoples of Minnesota. The first European settlers to arrive in Minnesota found native people already mining the area’s iron ore.
Today, taconite mining is a major industry in Minnesota, responsible for $3 billion in annual sales and thousands of jobs.
