LOL that’s not the only ass backward thing I said. The big open pit mines in Michigan are iron mines.
“The big open pit mines in Michigan are iron mines.”
My experience with open pit mining had to do with conveyor belt manufacturing...customers included Cleveland Clifts Empire Mine in Negaunee, MI and the Mesabi Range in MN - both iron ore operations. Btw, Cleveland Clifts has announced they are shutting down. Also supplied stuff to the Anaconda operations in AZ.
