U.S. Steel Corp. will temporarily idle its iron taconite plant in Keewatin, Minn., in May and begin laying off up to 412 workers, officials said Thursday.
It is the second iron-ore plant on Minnesota's Iron Range in three weeks to idle production. On Feb. 24, Magnetation LLC announced that it will idle its Keewatin plant, affecting 49 workers.
Now U.S. Steel's "KeeTac" taconite plant will follow suit.
Both companies' decisions are in response to crushed iron-ore pricing and high inventories around the globe. Australia, Brazil and U.S. production has soared while demand from China and other nations fell. At the same time, prices plunged from $95 a ton as recently as June to $58 a ton this week. That's down from $63 a ton on Feb. 25.
At U.S. Steel's plant, the precise number of employees affected by the May 13 shutdown of the plant, formally known as Minnesota Ore Operations-KeeTac, will be determined by operational and maintenance needs, the company said.
U.S. Steel said it will continue to produce iron ore pellets at its MinnTac plant in Mountain Iron.
Dan Kingsley, business representative for the International Union of Operating Engineers Local 49, said that rumors had swirled for weeks that KeeTac might shut down.
"Everybody could see for quite some time that the iron-ore prices globally were going down," he said. "But did anyone predict that they would go this low? No. Nobody did."
