Cleveland Cliffs purchased Henry Ford's Dearborn steel mill
from AK steel fairly recently. I now see that Cleveland Cliffs
is trying to purchase U. S. Steel.

U. S. Steel had a plant on Zug Island but announced in 2019
that they would soon shut that plant. However, U. S steel
continued to operate that plant after 2019.

Is U. S. Steel producing steel on Zug Island. What would
happen if Cleveland Cliffs purchased U. S. Steel? I suspect
the plant on Zug Island is only and not nearly as efficient
and cost effective as the recently modernized steel plant
in Dearborn.
