Zinc sheet metal is used to make zinc bars. 64 Zn, the most abundant isotope of zinc, is very susceptible to neutron activation, being transmuted into the highly radioactive 65 Zn, which has a halflife of 244 days and produces intense gamma radiation. Because of this, zinc oxide used in nuclear reactors as an anticorrosion agent is depleted of 64
Zinc ore occurs in two types of deposit: as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that ...

Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. With its low melting point of 420 °C (788 °F), unalloyed zinc has poor engineering properties, but in alloyed form the metal is used extensively. The addition ...
