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

摘要

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 respect to content of ZnO in the slag. The apparent activation energy of the (ZnO) reduction reaction is 312 kJ/mol at 1300-1500 deg c.
