Book Description
The treatment of electric arc-furnace and converter dusts has received considerable attention over the past ten years, as new and changing environmental legislation has been introduced. The most commonly practised commercial process is the Waelz kiln which is operated in the United States of America by Horsehead. The resulting clinker consists of low grade pre-reduced iron units that can in principle be recycled to the arc furnace. However, the zinc-enriched fume from the Waelz kiln is unsuitable for direct use in a conventional electrolytic zinc plant, but can be treated as such by a termal process (eg electrothermal - ZCA or an ISF plant).
