Zinc was a very useful metal for people of the ancient time in making of brass – an alloy of zinc and copper.Īlthough zinc was used to make brass, it was not isolated in its pure elemental form. Zinc is known to mankind since ancient time, but recent archeological facts suggest that zinc was first discovered by metallurgists before 1000 BCE. Zinc is produced by many countries but the largest producers are China, Australia, and Peru. Among them, the most widely available and mined mineral is sphalerite which gives zinc most economically. There are many minerals from which zinc can be extracted but the most economical minerals are smithsonite, sphalerite, wurtzite, and hemimorphite. Also, the oceans of the Earth contains dissolved compounds of zinc is minor quantity. Zinc element is abundant in many minerals found across the world but rarely found in the elemental form. Today, zinc is the 4 th most used metal in the world after iron, aluminum, and copper. It is also used in the dietary supplements, multi-vitamin tablets, and in sun-block creams. The human body also contains zinc and we require to eat food that contains zinc to maintain its level in our body. Today, it is also used to make alloys to achieve a metal of desired properties. Zinc has been used to make various alloys with other metals by the people of the ancient time – such as brass. Due to this reason, today most of the zinc produced each year is used to galvanize (coat) other metals such as iron to protect them from corrosion. Zinc is very good corrosion resistant metal and is cheap compared to most metals. Fairly good electrical and thermal conductor.Zinc has fairly good electrical conductivity than most of the metal. ![]() Due to its low boiling point, it was difficult for the people of the ancient time to isolate it in elemental form by heating its minerals. Zinc has fairly low melting and boiling points compared to most of the metals. But when it is heated to 100 centigrade of temperature, it becomes more malleable and easy to shape. It is not a good malleable metal slightly brittle at room temperature. Zinc is a moderately reactive element, when placed in the air its surface turns into dull white color.
