Metals Insider reported that US zinc producer Horsehead has started up a second Waelz kiln used to recycle zinc from electric arc furnace dust from the steel industry at its Rockwood facility in Tennessee.

The newly built kiln wills double the location’s current EAF processing capacity. Production, as with the existing kiln, will be sent for further processing to the company’s Monaca zinc refinery in Pennsylvania.

Horsehead has also announced plans to build another EAF dust recycling facility in the Carolinas to treat dust from steel producer Nucor’s plants in the area.

That follows an agreement with Nucor to expand the two companies’ existing commercial relationship to include Nucor’s three steel plants located in the Carolinas.
