Hayden Smelter, Copper smelter facility in Hayden, Arizona.
The Hayden Smelter is a copper processing facility in Arizona that refines ore from the Ray mine through a 305-meter chimney, the tallest structure in the state. The industrial complex contains multiple buildings and processing units that work together to transform raw copper ore into finished metal.
This facility was established in 1984 by the American Smelting and Refining Company, replacing an earlier Kennecott mining operation in the region. This transition marked a shift in how the area's industrial activities were managed and structured.
This facility forms the economic center of Hayden and has shaped the town's identity since its founding in the early 1900s. It remains deeply woven into how residents see themselves and their community.
The facility can be viewed from outside, and the chimney is visible from various points around town. Visitors should keep in mind that this is an active industrial site, so access and photography may be restricted in certain areas.
The facility operates under a specialized Superfund Alternative designation and manages extensive soil remediation projects across the surrounding area. These programs work to address environmental impacts from decades of mining and processing operations.
