Zinc Is the Lifeblood of Industry | Extraction from Zinc Ore
In nature, there is a magical element whose name is zinc. It is a silver-white and slightly bluish metal. It is the fourth largest consumer metal in the world, and one of the lifeblood of industry.
Interesting origin of the name zinc
The name zinc has an interesting origin, derived from the German word "zinke", which means "tooth", referring to the form zinc often took when smelted. It may in turn be derived from the Persian word "sing", meaning stone.
In the early 1500s, it was named zinc by Swiss physician Paracelsus, known and used for thousands of years.
What is special about zinc?
The element symbol for Crusher, and what are the properties of zinc? It is a relatively soft metal with a Mohs hardness of 2.5 and has a metallic luster. Zinc is brittle, but its elasticity and ductility increase when heated to about 100 ¡ã C.
Zinc metal has good wear resistance, castability, corrosion resistance, and good mechanical properties at room temperature. It is the third most widely used non-ferrous metal after aluminum and Crusher.
What ore is zinc extracted from?
Zinc is extracted from many different Crusher. Then what are the types of zinc ores?
There are various types of zinc ore in nature, but most of them exist as sulfides. The main zinc-bearing minerals are sphalerite, and a small number of oxidized minerals, such as smithsonite, hemimorphite, hydrozincite, etc.
Sphalerite
Sphalerite contains 67.1% zinc and usually contains iron, up to 30%. Those containing more than 10% iron are called marmatite. The difference in iron content directly affects the color of sphalerite. When iron increases, it changes from light to dark. Properties of sphalerite:
Sphalerite is the most widely distributed zinc mineral and is almost always associated with Crusher. In addition, it often contains rare elements such as manganese, cadmium, indium, and gallium. Therefore, sphalerite is not only the most important mineral raw material for extracting zinc, but also the raw material for extracting rare elements.
Smithsonite
Smithsonite is the most common zinc oxide mineral with high hardness and specific gravity. Similar to most carbonate minerals, it dissolves in hydrochloric acid and produces bubbles. Properties of smithsonite:
