Zinc Carbonate AMERICAN ELEMENTS

Zinc was first isolated by Andreas Marggraf in 1746. In its elemental form zinc has a silver-gray appearance. It is brittle at ordinary temperatures but malleable at 100 °C to 150 °C. It is a fair conductor of electricity and burns in air at high red producing white clouds of the oxide. Zinc is mined from sulfidic ore

Smithsonite The mineral smithsonite information and pictures

Smithsonite is composed of zinc carbonate but the zinc may be partially replaced with other elements. Those elements are responsible for the color variations. For example copper often causes green or bright blue colors and cobalt causes a pink to purple color. Cadmium makes Smithsonite yellow and iron gives it a brown to reddish-brown color.

How is zinc extracted from its carbonate ore (calamine

Zinc is extracted from its carbonate ore (calamine) when calamine ore is heated strongly in the absence of air i.e. calcined it decomposes to form zinc oxide and carbon dioxide. Then zinc oxide is heated with carbon and zinc metal is produced.

Zinc is used as coating to protect iron and steel from corroding in the atmosphere water and soil. This is because zinc reacts preferentially to iron in most environments to form protective layers of oxide carbonate or other zinc reaction products that are resistant to subsequent corrosion by the atmosphere.
