Doe Run Company Announced Mineral Extraction Technology Upgrades

Live Poll

Do you believe increasing domestic production of critical minerals makes the nation more secure?

The Doe Run Company has announced plans to improve its proprietary ACL HydroMet Process technology over the next year. This liquid-based chemical extraction method aims to enhance the recovery of critical minerals like cobalt, copper, and zinc.

Why it matters

The technology aims to reduce reliance on foreign supply chains for essential minerals by lowering operating costs to support lower-grade ore mining. This comes as the United States officially designated lead as a critical mineral in 2025.

The ACL HydroMet Process has been in development for 15 years and utilizes recycled ammonium chloride solutions to extract minerals without traditional smelting heat. The system has proven effective in a pilot facility for isolating multiple minerals.

The players

The Doe Run Company

This Missouri-based corporation specializes in mineral extraction and recycling, operating facilities that manage lead and other critical resources.

The details

The facility in Missouri, which operates as a recycling hub, uses this method to recover antimony, germanium, nickel, and tin alongside more common metals. By using liquid chemistry instead of extreme heat, the process minimizes environmental waste while keeping products like copper within North American markets.

1996: Doe Run transformed a lead smelter into a recycling facility.
2011: Development of the ACL HydroMet Process began.
2025: Lead was designated as a critical mineral by the United States.
October 5, 2026: The CEO discussed upcoming technology improvements.
October 2026-2027: Doe Run will implement improvements to its technology.

The Big Picture

The initiative aligns with the 2025 United States critical mineral designation for lead, which prioritizes domestic supply chain security. This move signals a paradigm shift toward refining internal extraction capabilities to satisfy national requirements for raw materials.

By increasing the efficiency of domestic mineral recovery, this technology could lower costs for materials used in green energy components and advanced electronics. This shift supports a more stable local economy in Missouri by ensuring the recycling facility remains competitive and sustainable.

The takeaway

Advancements in hydrometallurgy are essential for countries looking to process mineral assets without relying on overseas smelting capacity. For stakeholders, these technological improvements represent a long-term commitment to self-sustaining mineral life cycles within North America.
