Review of hydrometallurgical recovery of zinc from
Zinc ash is obtained in the dry galvanizing process due to the oxidation of molten zinc on top of the bath and floats on the surface of the molten zinc. The zinc ash normally contains its oxides and a small percent as free metallic zinc with some impurities in wt.% as 60–85 Zn, 0.3–2.0 Pb, 0–0.3 Al, 0.2–1.5 Fe, 2–12 Cl.
Contributions of Non-ferrous Smelters to Metal Resource …
Abstract. As contributions of non-ferrous smelters to metal resource circulation, ores and secondary raw materials, such as scrap and waste, are treated to recover base metals such as copper, lead, and zinc, as well as other precious and minor metals. One crucial factor that makes this metal recovery possible is the creation of an …
