This is interesting. Steel would be produced to the slab level right at the mine site cutting out, I guess, one level of transportation.
Construction of a $1.6 billion taconite-to-steel plant near Nashwauk can move forward, now that a Minnesota Pollution Control Agency board approved an air permit for the project. The pollution board voted for the permit 8-0 Friday after a hearing in St. Paul. The process was the last of many governmental approvals that Minnesota Steel needed to build the plant, which would be the nation’s first operation that produces steel at the site where the ore is mined.
