Laboratory Investigation of Zinc Recovery from EAF Dust by Bath Smelting Reduction

Bath smelting reduction for recovering zinc from EAF (Electric Arc Furnace) dust has been investigated in the laboratory. A degree of zinc volatilization of more than 99% was obtained from the process. Temperature has a clear influence on the reduction rate of ZnO in slag. The reduction rate of (ZnO) by [C] is the first order with respectto the content of ZnO in the slag. The apparent activation energy of the (ZnO) reduction reaction is 312kJ/mol at 1300??500℃.
