    The zinc oxide remains in the slag phase and the slag is subsequently treated by adding coal to reduce the zinc oxide to metallic zinc. The metallic zinc is removed by vaporization because of its low boiling point (707 °C). In the case of the ISF, the zinc oxide is simultaneously reduced with the lead oxide by carbon monoxide.

    From similar experiments, in which the proportions of zinc oxide and ferric oxide were varied, they concluded that no ferrates were formed that contain more zinc than ZnOFe2O3, but that when these oxides are heated for any length of time above 650° the iron will render one-half its equivalent of zinc insoluble.

  • Zinc smelting Wikipedia

    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
