Zinc Smelting Process

A smelting process of superior energy efficiency particularly suitable for the extraction of zinc but also of lead and copper from raw materials comprising sulphide concentrates and oxidized metalliferous materials is carried out by establishing at least one oxidation zone and at least one reduction zone in a furnace each zone comprising a slag bath and a gas space the gas spaces of the
