Monaca, PA

Conveniently positioned with access to road, rail and river transportation, Horsehead’s Monaca plant operates as the country’s largest zinc smelter. Located 28 miles north of Pittsburgh, this electrothermic zinc smelter is the result of a company experiment conducted in the 1920's to produce zinc oxide. Since that time, the Beaver County operation has been expanded and modernized. Recognized as the world’s largest user of recycled zinc-bearing materials in its manufacturing process, Horsehead's Monaca location produces primarily zinc metal and zinc oxide.
