Abstract
American Zinc Recycling Corp. operates five recycling plants with a capacity of over 650,000 tons per year for EAF dusts and zinc-containing residues and secondaries. AZR operates nine Waelz kilns at four plants: Chicago, IL, Rockwood, TN, Palmerton, PA and Barnwell, SC, and recovers nickel and zinc through its INMETCO plant (RHF/SAF) near Pittsburgh. Continuous improvements to the Waelzing process have increased productivity, decreased operating costs, enhanced Waelz Oxide quality, and minimized environmental impacts: temperature monitoring, air blast/oxygen-enrichment, feed conditioning, and refractory systems. AZR is reintroducing its Advanced Zinc Recovery (aka Flame Reactor) oxy-fuel flash-smelting technology to provide EAF steel producers with on-site dust processing that eliminates the liability and costs associated with EAF dust transportation. Restart of the Mooresboro, NC plant, based on Leach/SX/EW technology, will enable AZR to produce SHG zinc from Waelz Oxide, plus other zinc secondaries, at the rate of 155,000 tons per year. Restart is scheduled for April 2020 (Fig. 1).
