Both Copper and steel are processed heavily from scrap metal.  Steel/pig iron from blast furnaces, which require iron ore, is still done.  Impurities from/in scrap a problem.    Environmental problems associated with coke ovens, blast furnace also limit this process.  Recent air quality concerns, Edgar Thompson works, along the Monogahela River, Pittsburgh.

Not in Minnesota!  


A lot of copper was found and taken out of the western part of the Upper Penninsula of Michigan at one time. There are still some copper mines open to visitors. I did a tour of one years ago. Many refer to that area as "Copper Country."

There are a lot of copper/nickel deposits in northern Minnesota, an estimated 4 billion tons of copper, nickel and other valuable metals, but to date there has been little in the way of development and production. That may or may not happen in the future.

Iron ore is still mined and shipped from several parts of the Upper Penninsula of Michigan as well, such as Marquette and Ishpeming, which still have active ore docks. Lots of rail action to and from those docks.

We visited the Iron Range a few years ago. Sat up on hillside watching the mining operation. You can visit North Hibbing with its streets, sidewalks and no buildings. Plaques indicate which building was where before they moved everything. There’s also the very informative and transportation related Greyhound Bus museum. Worth checking out this area if you’re ever in MInnesota. Great post Don.
