Zinc and lead are mainly extracted by pyrometallurgy or pyrometallurgy combined with hydrometallurgy.1,2 With continuous exploitation of sulfide ores and high-grade zinc oxide ores, the remaining low-grade oxide ores, containing 1–10% Zn and 1–5% Pb, may be an important alternative.3 However, recovery of valuable metals, especially Zn, from oxide ores …
Introduction. The importance of zinc oxide ores processing such as carbonate and silicates minerals have increased because of the depletion of zinc sulphide ores and the restriction on sulphur emissions during their processing 1 – 6.The zinc oxide ores usually contain several different minerals including zincite (ZnO), smithsonite (ZnCO 3), hydrozincite (2ZnCO …
