Abstract (en)
The invention relates to a method for producing zinc from oxidic zinc raw materials by reducing them in carbonaceous iron melt. In the method the zinc raw material is injected, together with a carbonaceous reducer, into the iron melt, so that the oxidic zinc is reduced and volatilized as metallic vapour. This vapour is discharged from the iron melt together with the carbon monoxide released in the reduction reaction and the carrier gas, and is conducted out of the reactor into a separate condenser, where the zinc is recovered by condensing.
