Zinc and Lead Arkansas
Zinc (Zn) is a bluish-white lustrous metal that is brittle at room temperature, but malleable when heated. It has a low melting point (419.5°C) and a moderately high specific gravity (7.13). Lead (Pb) is a soft, ductile, malleable, bluish-white metal with a low melting point (327.4°C) and a high specific gravity (11.3). Zinc and lead minerals often occur together because, as elements, they
Lead and Zinc Smelting IFC
Lead and Zinc Smelting Industry Description and Practices Lead and zinc can be produced pyrometal-lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet-allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-

Metallography of Lead, Tin and Zinc Metals and Alloys
Description: Lead, tin and zinc are unique materials because they each have a recrystallization temperature below room temperature. Preparation Challenge: The difficulty in preparing these metals for microstructural analysis is that they do not work harden and thus their microstructure can be altered simply by incorrect specimen prepration.
