Mineral wealthy Minnesota offers more than ore
29 Jun 2020
“Every single county in Minnesota has a mine.”
Heather Arends, mineral potential manager for the Minnesota DNR, knows the state’s mining industry spans far beyond the edges of its massive iron ore extractions and, as she notes, into all 87 counties.
Minnesota has multiple thriving operations considered “mining,” whether it’s harvesting peat, carving slabs of granite or extracting Kaolin clay. Some materials travel across the ocean to other countries; others, like aggregate gravel and sand needed for unpaved roads or general road upkeep, rarely leave a county.
