US Steel Receives Approval to Expand Minntac Mine Area
U.S. Steel’s Minnesota Ore Operations on the Mesabi Iron Range in northern Minnesota include Minntac at Mountain Iron and Keetac at Keewatin. Taconite is mined and processed into iron ore pellets for use in U. S. Steel’s steelmaking facilities. Pellet production capabilities are approximately 16 million short tons per year (st/y) at Minntac and 6 million st/y at Keetac.
Subsequently, U.S. Steel announced on September 16 that it will not pursue an expansion of its Keetac operations. The expansion would have increased Keetac pellet production by 3.6 million st/y to a total of 9.6 million st/y and included upgrading and restarting an idled pelletizing line and upgrading the mining, concentrating and agglomerating processes. The permits required for this expansion expired in September and will not be renewed.
