Franklin-Sterling zinc operations consolidated into New Jersey Zinc in 1852 after which the Company acquired the Palmerton facility in the Lehigh Valley to build a zinc smelting plant. This resulted in the plant and town incorporated into the City of Palmerton in 1912. A railroad for the facility called Chestnut Ridge Railroad was laid in 1905.
Lots of history occurred in this plant, and we plan to continue the legacy of growth by processing EAF dust in 3 kilns.

What happens here?
At our recycling facilities, EAF dust is fed along with coke or coal into a Waelz kiln, which is a large, rotating metal tube. In the kiln the EAF dust is tumbled and heated to a temperature where certain non-ferrous metals are vaporized. Air is drawn through the kiln and the metal vapors are oxidized to form solid metal oxide particulates which, once collected, is WOX. Air from the kiln passes through a product collector where the WOX is gathered. WOX is a light gray metal oxide powder, that contains 60% zinc oxide. Other metal oxides recovered in WOX include lead oxides, cadmium oxides, and chromium oxides.
The remaining portion of EAF dust that exits the kiln is Iron-Rich Material, referred to as IRM. IRM contains 40% iron oxide and other minerals, and once tested to ensure hazardous metals have been removed, can be sold to asphalt, cement, or aggregate companies, and it can even go back into the steel production process.
