Although zinc compounds were used in ancient times, pure metallic zinc was first isolated in India around the 12th century and later identified as an element by Andreas Sigismund Marggraf in 1746.
Zinc occurs naturally in minerals such as sphalerite, smithsonite and zincite. Sphalerite is the world's most important zinc ore.

Zinc is widely used for galvanizing steel, manufacturing brass, making batteries, die-casting automobile parts and producing many industrial chemicals.
Copper, Iron, Magnesium and Oxygen
Zinc reacts readily with acids and strong alkalis. In moist air it develops a thin protective oxide layer that slows further corrosion.
Electronic Configuration: [Ar] 3d¹⁰ 4s²
Zinc's greatest strength is its ability to protect iron and steel from rust through galvanization, greatly extending the lifespan of structures and machinery.
Nearly half of all zinc produced worldwide is used to galvanize steel, protecting bridges, buildings, vehicles and pipelines from corrosion.
Steel coated with zinc is called galvanized steel. Even if the coating is scratched, zinc continues protecting the underlying iron through sacrificial corrosion, making it invaluable for outdoor structures.
Brass is an alloy of copper and zinc. It combines strength, corrosion resistance and an attractive golden appearance, making it useful for musical instruments, plumbing fittings, locks and decorative items.
Zinc serves as the anode in dry-cell, alkaline and zinc-carbon batteries. It is also used in emerging rechargeable zinc-air and zinc-ion battery technologies.
Zinc is an essential trace element required for immunity, wound healing, growth, DNA synthesis and the proper functioning of more than 300 enzymes in the human body.
Zinc is used in die-casting, paints, rubber, cosmetics, pharmaceuticals, fertilizers, electrical equipment and protective coatings for industrial machinery.
Zinc oxide is widely used in sunscreens because it reflects and scatters harmful ultraviolet (UV) rays. It is also found in skin creams, cosmetics, rubber products and protective coatings due to its excellent stability and safety.
Zinc is an essential micronutrient for plants. Zinc deficiency can reduce crop yields, so zinc-containing fertilizers are widely used to improve agricultural productivity and food quality.
Researchers are developing zinc-air batteries, biodegradable zinc alloys for medical implants and environmentally friendly corrosion-resistant coatings for sustainable industries.
Zinc is formed during the explosive deaths of massive stars and distributed throughout the universe by supernovae, becoming part of future stars, planets and living organisms.
India was one of the earliest civilizations to produce pure metallic zinc on a large scale. Ancient zinc smelting sites at Zawar in Rajasthan are considered remarkable achievements in the history of metallurgy.
