Patent

CA 2151195

A method making pig iron employs an in-bath direct reduction performed in a metallurgical vessel which has above it a melting cyclone in which iron- oxide-containing material fed thereinto is pre-reduced by hot reducing gas coming from the vessel. Molten material passes downwardly from the melting cyclone into the vessel. In order to recover zinc from a dust containing zinc and/or zinc oxide, the dust is fed into the melting cyclone. Zinc is allowed to vaporize out of the dust into the hot gas in the melting cyclone. The hot gas containing zinc is discharged from the melting cyclone, and zinc-containing material is extracted from this hot gas.
