Figure 4 Leaching of zinc oxide. As mentioned above, some of the zinc oxide is present with iron(III) oxide in the form of zinc ferrite. Several variations on the leaching process are used to separate zinc from impurities. Most of these use hot acid conditions to produce a mixture of zinc and iron(III) sulfates, followed by removal of the iron ...
3) One method of extracting zinc involves the reaction of zinc oxide with carbon. Explain, both in terms of oxygen and electrons, why this extraction is involves reduction. zinc ions gain electrons (Zn2+ + 2e– → Zn) zinc oxide loses oxygen 4) Lead is extracted by the reduction of lead oxide by heating with carbon: PbO + C → Pb + CO .
