Zinc Ore / Lead Zinc Ore
Zinc Ore_Lead

About 70% of the world's zinc originates from mining, while the remaining 30% comes from recycling secondary zinc. It is the fourth most common metal in use and the 24th most abundant element in the world comprising of about 75 ppm (0.0075%) of Earth's crust. The most common zinc ore is sphalerite. The symbol for Zinc is ‘Zn’ and the atomic number is 30. Zinc is chemically similar to magnesium in the sense that both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.

Zinc is a brittle, crystalline, bluish white metal and is principally mined as the primary sulphide sphalerite, usually in association with galena. Sphalerite contains 67% Zn and often includes traces of cadmium, gallium, germanium and indium as simple sulphides in solid solution.


Zinc is mainly used to galvanize steel or iron that is to apply a zinc coating to stop it rusting. Galvanized steel is used in buildings, cars and electronics. The strength and flexibility of zinc alloys mean they are widely used to create die casts for industrial uses. Zinc is also used to make brass and bronze. Zinc oxide is mainly used in the production of rubber, while zinc sulphide has uses such as X - ray screens, in optics, and as a pigment. Zinc compounds and dusts are used in cosmetics, plastics, rubber, ointments, sun screen creams, soaps, paints, ink, fertilizers and batteries.
