Another shoe has dropped on the Iron Range, with U.S. Steel announcing Tuesday that it will idle parts of its Minntac taconite plant, the third Minnesota iron-ore operation to announce a shutdown in six weeks.
Roughly 700 hourly and salaried workers are likely to be affected by the June 1 idling of the plant in Mountain Iron, said officials from United Steelworkers District 11.
The news comes just three weeks after Pittsburgh-based U.S. Steel said it would idle its Keetac taconite plant in Keewatin, affecting 412 workers. Six weeks ago, iron ore processor Magnetation said it would indefinitely idle its Keewatin plant, affecting about 20 workers.
The shutdowns — which have prompted worry among legislators and even in the White House — are in response to imports of low-cost steel from South Korea, India, China and other nations that have flooded the United States in the past year.
Taconite producers also face high inventories of iron ore because Australia, Brazil and U.S. producers have increased ore production.
In response, prices of taconite — a key component in making steel — have plunged from $95 a ton as recently as June to less than $60 a ton in March. As a result, U.S. producers are cutting back.
Last week, U.S. Steel announced it will idle its flat-rolled steel plant in Granite City, Ill. This week it was Mountain Iron, and many fear a domino effect of plant closings may just be starting.
The Iron Range, in the northeast corner of the state, is home to eight iron-ore mining or processing operations. A ninth, Essar Steel Minnesota, is under construction. With so many plants tied to the same product, producers, residents, politicians and economists are nervous about where the current trend will lead.
