How Is Zinc Obtained? |
Zinc ore is crushed to separate the zinc from other elements, then roasted or sintered to produce zinc oxide before an electrolytic process is used to obtain the zinc. Zinc ore contains only 5 to 15 percent zinc. After roasting the ore, sulphuric acid is added.

India Was the First to Smelt Zinc by Distillation Process
Smelting process of zinc. Craddock et al (1985) have mentioned that distillation technology and apparatus were used in ancient times in India for the process of distillation of water, wine, mercury and zinc. The process used for the distillation of zinc in Zawar mines is unique because it is designed on the basis of downward distillation.

Zinc and Lead
Zinc is mainly used to galvanise steel or iron – that is, to apply a zinc coating to stop it rusting. Galvanised steel is used in buildings, cars, white goods and electronics. The strength and flexibility of zinc alloys mean they are widely used to create die casts for industrial uses – for example, in the production of car or machine parts.
