Magnitude 7 Metals, the owner of a primary smelting facility in Marston, Missouri, that previously was operated by Noranda, has announced plans to restart production there.
David Kaplan from Delaware-based Otto Von Blue LLC, the owner of Magnitude 7 Metals says “Today’s announcement represents more than the return of production—it reflects renewed confidence in America’s industrial strength and future.”
He continues, “We are proud to restore critical domestic aluminum capacity, creating hundreds of new good-paying manufacturing jobs in Marston, Missouri, and invest in the long-term resilience of American manufacturing. President Trump’s 50 percent aluminum tariff has created the conditions for that investment.”
The facility has been closed since 2024, reportedly in part because Magnitude was having difficult paying for clean air-related environmental compliance costs.
The potential reopening of a 75,000 tons per year potline or smelting production line is being applauded by some metals industry trade groups but met with caution by non-governmental organizations concerned about pollution.
