The general outline of the distillation process employed at Mikkaichi Zinc Smelter has been previously published in the December 1956 issue of this journal. A more detailed report is given here as the operating conditions at this smelter have since then become more stabilized.
At present 3 electric furnaces are installed with a total average monthly production of 1000 metric tons of spelter. Metal recovery from the concentrates averages 90%. The total consumption of coke is 720kg/t and electric power 3750kWh/t. There is further scope for improving these results to some extent.
