What We Do

Responsible Mining and Metal Production

Doe Run has operated for nearly 160 years as a responsible mining and metal production company.

From exploration and development of new mineral resources, to recycling lead batteries and other lead-bearing materials, we are integral to the full lifecycle of lead. Our mining operations make up one of the largest lead mining districts in the world. Located in Southeast Missouri, our mines deliver lead, copper and zinc concentrates across the globe. We provide metal fabrication through our Seafab Metals Company subsidiary in Arizona and Washington. And, we operate one of the world’s largest single-site lead battery recycling plants, also located in Missouri, returning valuable lead metal and alloys to future use in batteries and essential products.

Our goal is to operate as a good neighbor through responsible mining and metal production. Learn More About Who We Are.

Our Minerals are Used Every Day

Providing Sustainable Energy
  • Lead batteries, like those that power vehicles, are the most recycled consumer product on the planet.
  • Every U.S. mass-produced car and truck in the U.S. (more than 270 million), including electric vehicles, use lead batteries.
Powering Your World
  • Copper wire conducts electricity that powers your home and runs your electronics. Copper makes up more than 12 percent of your cell phone’s weight.
  • Lead batteries store power from electric generation and from alternative energy sources, like solar and wind. Hospitals and cities also rely on these large lead batteries for back-up power in emergency situations.
Protecting Your Health
  • Lead is an essential element in radiation shielding, including large-scale nuclear waste storage containers to small nuclear medicine containers, and is commonplace in X-ray facilities.
  • Adequate levels of zinc reduce childhood illnesses, enhance physical growth and decrease mortality in developing nations.
Building the World’s Infrastructure
  • More than 65 percent of zinc sold galvanizes steel used in construction, automotive and machinery industries.
  • Lead is used in lead rubber bearings to help stabilize buildings and bridges during earthquakes.
