Abstract
A major objective of the zinc industry for the 1990s will be to maintain high zinc recovery while eliminating the disposal of copious quantities of hazardous iron residues The flame reactor process has demonstrated the potential of meeting this objective by either treating the residues or smelting zinc directly The process has been proven commercially viable for treating flue dusts generated during electric arc furnace steelmaking Zinc lead and cadmium are recovered from the dust as a crude oxide for recycle while a nonhazardous slag is produced for sale Similar products are efficiently produced from electrolytic zinc plant neutral leach and iron precipitation residues In addition the reactor shows promise of fulfilling its original objective of being a lowenergy primary zinc smelter by fuming and condensing zinc from roasted concentratesJF Pusateri received his MS in materials engineering from Drexel University in 1975 He is currently director—flame reactor operations and development for Horsehead Resource Development Company Inc MRR Division Mr Pusateri is also a member of TMSCO Bounds received his PhD in metallurgy and materials science from Carnegie Mellon University in 1971 He is currently director—business development for Horsehead Resource Development Company Inc MRR Division Dr Bounds is also member of TMSLW Lherbier Jr received his BS in metallurgy and materials science from Carnegie Mellon University in 1980 Mr Lherbier is currently a senior process engineer with Horsehead Resource Development Company Inc MRR Division Mr Lherbier is also a member of TMS
