    Zinc processing | Britannica.com

    History. The separation of metallic zinc from its ores by pyrometallurgy is much more difficult than with other common metals, such as copper, lead, and iron, because the reduction of zinc oxide by carbon (C) proceeds spontaneously only above the zinc boiling point of 907 °C (1,665 °F). Efficient methods of condensing the vapour to liquid metal were not discovered until the 14th century.

    Redox reaction from dissolving zinc in copper sulfate ...

    And we'll look at the half reactions in a second. You get a redox reaction where the copper takes electrons from the zinc. So it becomes neutral solid copper. And the zinc loses those electrons to the copper. And so those become zinc cations. Or you could think of it as zinc sulfate dissolved in the aqueous solution. So let me write that down.
