ABSTRACT:
A method of smelting zinc in a blast furnace wherein the furnace is charged sequentially with separate loads of coke and agglomerated zinc oxide material, wherein, for a major proportion of the total operating time which is devoted to coke charging, from 25% to 50% by weight of the coke charged is directed towards the center of the furnace shaft so as to promote a coke-rich charge core, the remainder of the coke charged being directed towards the furnace walls, and wherein for a minor proportion of the said total operating time from 80% to 95% by weight of the coke charged is directed towards the walls of the furnace shaft to aid accretion melting, the remainder of the coke charged being directed towards the center of the furnace shaft.
