U.S. Steel Corp. said Tuesday it plans to idle part of its Minntac plant at Minnesota’s biggest iron mine, resulting in about 680 layoffs. It’s the latest symptom of a downturn in the American steel industry that has taken a heavy toll on the Iron Range of northeastern Minnesota.
U.S. Steel has received the final federal permits necessary to move ahead with expanding its Minntac iron mine and processing facility in Mountain Iron. A joint announcement from the company and the United Steelworkers union says the 483-acre expansion will allow the state’s largest taconite operation to keep operating for around 16 more years.
United States Steel Corp. has now received the state permits it needs to expand its Minntac mine at Mountain Iron but is waiting on one remaining federal permit.
