2021-1-21 · IRON MINING TODAY Open pit mining for iron ore replaced shaft mining very early on in the history of the Michigan Iron Ranges. Today, all the underground mines are closed, and only a very few open pit mines are still operating. What remains of the underground mines is often only a few heaps of waste rocks (below) and some slumped landscapes.

Major Mines & Projects

Northshore Mining Company (NMC) currently mines taconite, a low-grade iron ore, at its Peter Mitchell mine, which is located near Babbitt, St. Louis County, Minnesota. The crude ore is transported by rail from the mine to NMC's taconite processing facility (Facility), located on the north shore of Lake Superior in Silver Bay, Lake County
