In the American process, zinc ore or concentrate is mixed with coal and charged into an aerated furnace. The zinc ore is reduced momentarily to zinc vapor by the heat of combustion of coal in air. Carbon dioxide and excess oxygen in the furnace oxidize the zinc vapor to zinc oxide fume which is sucked out by large fans through pipelines to settling chambers and cloth filters for
