Abstract

PURPOSE: To continue a steady operation in a condenser while decreasing the generation of dross and improving a winning rate of zinc by floating lumped or granular coke at all times on the matte surface in a smelting furnace and sealing the slag surface.
CONSTITUTION: Sintered zinc ore is changed together with a reducing agent and air enriched with oxygen into a smelting furnace and is smelted. The formed zinc vapor is condensed and captured with a condenser provided integrally with the smelting furnace. Coke powder and/or pulverized coal, etc. are used as a reducing agent in the smelting stage and the top surface of the slag phase formed in the smelting chamber of the smelting furnace is covered with said coke powder or pulverized coal. Then, a substantial injection depth is assured and even if the sintered zinc ore and reducing agent floats temporarily on the matte surface, these powder materials are captured by the coke layer and the scattering thereof to the condenser is prevented.
