Where did zinc get its name? A German alchemist name Paracelsus named the metal zinc. It either comes from the German word “zinke” meaning “spiked” (for the spiked shapes of the zinc crystals) or “zinn” meaning “tin”. There are five isotopes of zinc that occur in nature.
Zinc was rediscovered by Andreas Sigismund Marggraf in 1746 by heating calamine with charcoal. Today, most zinc is produced through the electrolysis of aqueous zinc sulfate (ZnSO4).
Zinc is mined in over 50 countries with Canada being the leading producer, followed by Russia, Australia, Peru, United States and China. Deposits of zinc-bearing ores are found in most provinces of Canada, as well as in the Yukon and North West Territories.
In Mineral Commodity Report 6-Lead and Zinc (PDF-file) is said that it is derived from the Greek zink. Greek Ψευδαργυρος [pseudargyros]: literaly “pseudo-silver”.
History. The element zinc was discovered in Germany in 1746 by Andreas Marggraf. However, zinc ores were commonly used to make brass as early as 1400 to 1000 B.C. in Palestine and an “alloy containing 87 percent zinc was discovered at prehistoric ruins in Transylvania,” according to Web Elements.
Zinc is found in cells throughout the body. It is needed for the body’s defensive (immune) system to properly work. It plays a role in cell division, cell growth, wound healing, and the breakdown of carbohydrates. Zinc is also needed for the senses of smell and taste.
Metallic zinc was first produced in India sometime in the 1400s by heating the mineral calamine (ZnCO3) with wool. Zinc was rediscovered by Andreas Sigismund Marggraf in 1746 by heating calamine with charcoal. Today, most zinc is produced through the electrolysis of aqueous zinc sulfate (ZnSO4).
- Zinc has a self-healing mechanism in it. …
- Zinc melts at 787 F (420 C), and boils at 1,665 F (907 C).
- Zinc comprises an estimated 0.004% of the Earths crust.
- Zinc ranks 24th in order of material abundance in the Earth.
It is found in metamorphic, igneous, and sedimentary rocks in many parts of the world. Sphalerite is the most commonly encountered zinc mineral and the world’s most important ore of zinc.
Zinc and soluble zinc compounds are harmful to the environment at current levels of exposure, the Canadian government has provisionally concluded. In particular, the substances may pose a risk to aquatic organisms through release of zinc to water from metal mining effluent.
Group 12, by modern IUPAC numbering, is a group of chemical elements in the periodic table. It includes zinc (Zn), cadmium (Cd) and mercury (Hg).
Americium – Element information, properties and uses | Periodic Table. Americium is named for America where it was first made.
1 Zinc ores are dug from underground mines using conventional blasting, drilling, and hauling techniques. The ores occur as zinc sulfide (also called sphalerite), zinc carbonate (smithsonite), zinc silicate (calimine), and in compounds of manganese and iron (franklinite).
Zinc is a very common substance that occurs naturally. … Zinc occurs naturally in air, water and soil, but zinc concentrations are rising unnaturally, due to addition of zinc through human activities. Most zinc is added during industrial activities, such as mining, coal and waste combustion and steel processing.

Zinc is a mineral essential to many aspects of health. Supplementing with 15–30 mg of elemental zinc daily may improve immunity, blood sugar levels, and eye, heart, and skin health. Be sure not to exceed the upper limit of 40 mg.
Yes, if you get too much. Signs of too much zinc include nausea, vomiting, loss of appetite, stomach cramps, diarrhea, and headaches. When people take too much zinc for a long time, they sometimes have problems such as low copper levels, lower immunity, and low levels of HDL cholesterol (the “good” cholesterol).
This particular study concluded that in males, zinc has a positive effect on arousal and maintaining an erection. A 2013 study shows that sense of smell may actually be important to libido, especially in younger men. That means that zinc deficiency, which can reduce sense of smell, may also reduce libido.
- A penny made after 1982 has a zinc core.
- Alkaline and zinc-carbon batteries.
- Zinc air batteries for laptops.
- Nuts and bolts are sometimes zinc-plated.
- Organ pipes.
- Many toys.
- Replacement for lead.
Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposit on the cathodes (aluminium sheets) and oxygen to form at the anodes.
In 1668, a Flemish metallurgist, P. Moras de Respour, reported the extraction of metallic zinc from zinc oxide, but as far as Europe was concerned zinc was discovered by the German chemist Andreas Marggraf in 1746, and indeed he was the first to recognise it as a new metal.
The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
Input Prices Mining and refining zinc requires ample supplies of coal, electricity and crude oil. These costs can have a big effect on primary production.
Zinc is needed for DNA synthesis, immune function, metabolism and growth. It may reduce inflammation and your risk of some age-related diseases. Most people meet the RDI of 11 mg for men and 8 mg for women through diet, but older adults and people with diseases that inhibit zinc absorption may need to supplement.
Zinc: isolation Most zinc production is based upon sulphide ores. These are roasted in industrial plants to form zinc oxide, ZnO. This may be reduced with carbon to form zinc metal, but in practice ingenious technology is required to ensure that the resulting zinc does not contain oxide impurities.
Alaska is by far the most important U.S. state based on zinc mine production. It produced some 620,000 metric tons of zinc in 2018. Other U.S. states with significant zinc production from mines are Idaho, Missouri, Washington, and Tennessee.
Shellfish like oysters, crab, mussels and shrimp can all contribute to your daily zinc needs.
But for practical purposes zinc is not magnetic.
The great majority of zinc deposits contain the lead mineral, galena, and both the lead and zinc minerals are mined together. Other metals that are found with zinc are silver and copper.
In ordinary conditions, zinc reacts rapidly with air, gradually forming a dull grey zinc oxide coating. Additionally, zinc reacts with halogens, oxygen, chalcogens, alkalis, acids, ammonia and ammonium salts, and even with less active metals. Zinc reacts with both acids and alkalis, making it an amphoteric metal.
The heaviest element that occurs in large quantity is uranium (atomic number 92).
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
