# US Magnesium **Type:** venture **Status:** Draft **Confidence:** Medium **Focus:** primary magnesium production, critical minerals, Great Salt Lake brine, aerospace and defense metals, industrial process engineering **Stage:** Established industrial producer (Chapter 11 filed September 2025; asset sale in progress) **Location:** Rowley, UT (Tooele County, western Great Salt Lake shore) **Updated:** 2026-06-18 **Needs-reviewed:** 2026-06-18 **Hero:** https://picsum.photos/seed/us-magnesium-great-salt-lake-rowley-2026/1600/1100 **Pull:** *North America's largest primary magnesium producer — strategic metal from Great Salt Lake brine, now in bankruptcy.* ## Summary US Magnesium LLC operates the largest primary magnesium production facility in North America at Rowley, Utah, on the western shore of the Great Salt Lake. Magnesium has been produced at the site since 1972. The company extracts magnesium from high-salinity brine through solar evaporation and electrolytic cells, supplying a metal that is roughly 30% lighter than aluminum and strategically important for aerospace, automotive lightweighting, electronics, and defense applications. [source:us-magnesium-official-website] For the wiki, US Magnesium is not a frontier-tech startup but one of Utah's most consequential industrial operations — and one now in active financial and environmental crisis. The company filed Chapter 11 on September 10, 2025; court records and reporting describe EPA Superfund status, a January 2026 asset auction, and a reported winning bid by the Utah Division of Forestry, Fire, and State Lands.

The U.S. has essentially one commercial-scale domestic primary producer: this Rowley facility. Defense and aerospace programs requiring non-China-sourced magnesium effectively trace supply questions here. That makes US Magnesium a national-security-relevant supplier when it is operating — and a supply-chain vulnerability when it is not. The company is also embedded in the Great Salt Lake story. Brine extraction is among the larger industrial activities on the lake, and the operation has been contentious with preservation advocates over lake level, exposed-bed dust, and emissions. Impact is therefore both strategic-metals supply and environmental externality — not a simple "good employer" narrative. ## What They Are Building US Magnesium produces primary magnesium metal and related products from Great Salt Lake brine. The process involves solar evaporation ponds, electrolysis at high temperature, and hazardous chlorine handling — chemically complex, energy-intensive, and environmentally exposed. The company markets advanced electrolysis technology and solar-energy use, and has described development of lithium carbonate production from magnesium-production tailings in bankruptcy filings. [source:us-magnesium-bankruptcy] Whether magnesium production continues under new ownership, and on what environmental terms, is an open question as of mid-2026. ## What They Need Now In a stable scenario, needs would include chemical and electrochemical process engineers, metallurgists, industrial maintenance specialists, and environmental-compliance engineers. During bankruptcy and ownership transition, hiring posture, capital investment, and operational continuity are all uncertain. Anyone evaluating employment or supply relationships should verify current status directly. ## Who Could Help Useful helpers include environmental counsel and Great Salt Lake policy stakeholders, metals-trading and defense supply-chain advisors, bankruptcy and restructuring counsel, and Utah state agencies involved in the asset sale. Companies seeking domestic magnesium should treat supply as contingent until post-bankruptcy operations are confirmed. ## Utah Context US Magnesium is a quiet but load-bearing piece of Utah's industrial base and the national critical-minerals conversation. It sits alongside newer Great Salt Lake ventures (lithium, magnesium recycling startups) that aim for cleaner extraction — a contrast worth noting. The Renco Group affiliation and decades of EPA enforcement history complicate any uncritical celebration of the facility. ## Evidence - [Official Website: US Magnesium](us-magnesium-official-website.md) - [Source: US Magnesium Chapter 11 Bankruptcy and Asset Sale](us-magnesium-bankruptcy.md) ## Open Questions - Who ultimately owns and operates the Rowley facility after the January 2026 auction, and does primary magnesium production resume? - What are current employment levels and hiring plans under new ownership? - How do lithium-from-tailings plans interact with lake-preservation goals? - Environmental and labor history (EPA Superfund, emissions litigation, past safety incidents) should be read before treating this as an unqualified "meaningful work" destination. - Imagery is a deterministic placeholder pending a license-clean site photograph.
