The Extraction of Lead. Because its position in the reactivity series of metals, lead can be extracted using carbon (coke) in a smelting furnace.Because lead is below carbon, that is less reactive than carbon, lead can be displaced by carbon from lead oxides or lead sulfides in a sort of displacement reaction. The principal ore of lead is galena, chemical formula PbS lead .Zinc phosphide - WikipediaZinc phosphide (Zn 3 P 2) is an inorganic chemical compound.It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. Zn 3 P 2 is a semiconductor with a direct band gap of 1.5 eV and may have applications in photovoltaic cells. A second zinc phosphide is known, with the stoichiometry ZnP 2.extraction method of zinc in 50 words - guestroom-perroy.chExtraction of metals from a zinc smelting SpringerLink. Abstract. A two-step leaching method in combination of acid and ethylene diaminetetraacetic acid disodium (EDTA-Na 2) was applied to extract metals such as Cd Cu Fe Pb and Zn from a zinc smelting slag.The results show that the extraction rates of Cd Cu Fe and Zn in slag reach 88.3 54.1 69.6 and 54.7 respectively while the extraction .Extraction of Zinc - QS StudyExtraction of Zinc Zinc blende is concentrated by floath floatation process. The pulverized ore is kept in large tank containing water and pine oil. The mixture is agitated by passing compressed air.
