Zinc was discovered before it was officially discovered. In 1746, German chemist Andreas Marggraf (also the inventor of a process to extract sugar from beets) figured out how to isolate zinc by heating carbon and calamine (the stuff in calamine lotion).
How is zinc found in nature?
Zinc is present not only in rock and soil, but also in air, water and the biosphere – plants, animals and humans. Zinc is constantly being transported by nature, a process called natural cycling. Rain, snow, ice, sun and wind erode zinc-containing rocks and soil.
How is zinc formed in the earth?
Deposits containing zinc form from hot, aqueous (or hydrothermal) fluids generated within the earth. These fluids may flow along sub-surface fractures where sphalerite and other minerals may precipitate to make vein deposits. Where limestones occur, the fluids may flow through cavities to form rich but patchy deposits.

Postlewayt's Universal Dictionary, a contemporary source giving technological information in Europe, did not mention zinc before 1751 but the element was studied before then.
Where is zinc found?
Zinc mines at Zawar, near Udaipur in India, have been active since the Mauryan period ( c. 322 and 187 BCE). The smelting of metallic zinc here, however, appears to have begun around the 12th century AD. One estimate is that this location produced an estimated million tonnes of metallic zinc and zinc oxide from the 12th to 16th centuries. Another estimate gives a total production of 60,000 tonnes of metallic zinc over this period. The Rasaratna Samuccaya, written in approximately the 13th century AD, mentions two types of zinc-containing ores: one used for metal extraction and another used for medicinal purposes.
What are binary compounds of zinc?
Binary compounds of zinc are known for most of the metalloids and all the nonmetals except the noble gases. The oxide ZnO is a white powder that is nearly insoluble in neutral aqueous solutions, but is amphoteric, dissolving in both strong basic and acidic solutions. The other chalcogenides ( ZnS, ZnSe, and ZnTe) have varied applications in electronics and optics. Pnictogenides ( Zn#N#3N#N#2, Zn#N#3P#N#2, Zn#N#3As#N#2 and Zn#N#3Sb#N#2 ), the peroxide ( ZnO#N#2 ), the hydride ( ZnH#N#2 ), and the carbide ( ZnC#N#2) are also known. Of the four halides, ZnF#N#2 has the most ionic character, while the others ( ZnCl#N#2, ZnBr#N#2, and ZnI#N#2) have relatively low melting points and are considered to have more covalent character.
How long does zinc help with diarrhea?
Zinc becomes depleted in the body during diarrhea and replenishing zinc with a 10- to 14-day course of treatment can reduce the duration and severity of diarrheal episodes and may also prevent future episodes for as long as three months. Gastroenteritis is strongly attenuated by ingestion of zinc, possibly by direct antimicrobial action of the ions in the gastrointestinal tract, or by the absorption of the zinc and re-release from immune cells (all granulocytes secrete zinc), or both.
What is the melting point of zinc?
For a metal, zinc has relatively low melting (419.5 °C) and boiling points (907 °C). The melting point is the lowest of all the d-block metals aside from mercury and cadmium; for this reason among others, zinc, cadmium, and mercury are often not considered to be transition metals like the rest of the d-block metals.

The element zinc was not known as an element for a long time. Zinc has been used for thousands of years as an alloy, until its discovery in the middle of the 18th-century. The person who discovered and recognized zinc as a separate pure metallic element was Andreas Margraaf in 1746.
Who discovered zinc?
The discovery of zinc is attributed to the German chemist Andreas Marggraf, who, in 1746, isolated zinc and recognized it as a new metal. The alchemist, Paracelsus, gave zinc its name, derived from the German word "Zinke" meaning prongs.
Why is zinc used in iron?
One of the well-known uses of zinc is to protect iron articles as zinc is resistant to corrosion. Iron articles are immersed in a bath of molten zinc to coat them with zinc. The coating prevents the iron articles from rusting. Zinc undergoes sacrificial oxidation in preference to iron when air and water attack the metals.
Why is zinc misclassified as an element?
The reasons zinc element was misclassified included its reactivity and its low boiling point. Metals like copper and lead were obtained by smelting their oxides with coal in open furnaces. When subjected to a similar treatment, zinc escaped as vapor. If smelted with copper nuggets, it turned into alloy brass a process which caused zinc to lag behind other elements in its isolation and identification.
How much zinc is needed for living things?

When was zinc first made?
The realization that to make zinc it was necessary to produce the metal as a vapour and then condense it seems first to have been reached in India in the 13th or 14th century. The metallurgists of China had achieved large-scale production of zinc by the 16th century. In the West this principle was first applied in England in 1743 under the leadership of William Champion. At the end of the 18th century in Belgium and Poland improvements were made in the furnace, and the process remained unchanged until an electrolytic process was developed in 1917. At the end of the 1920s a radical advance was made in the United States by developing a continuous retort process, and during the 1930s an electrothermic process was designed for producing zinc continuously. A development of the 1960s was the zinc-lead blast furnace, in which rapid quenching of the gases is a key principle. Zinc production processes are treated in detail in zinc processing.

What metals can be molten?
Metallic zinc appeared much later in history than the other common metals. Copper, lead, tin, and iron can be obtained as the molten metals by heating their oxide ores with charcoal (carbon), a process called reduction, in shaft furnaces, which were developed quite early in history. Zinc oxide, however, cannot be reduced by carbon ...
When did the Romans make brass?

When was the electrolytic process invented?
At the end of the 18th century in Belgium and Poland improvements were made in the furnace, and the process remained unchanged until an electrolytic process was developed in 1917 .
Can zinc oxide be reduced?
Zinc oxide, however, cannot be reduced by carbon until temperatures are reached well above the relatively low boiling point of the metal (907 °C). Thus, the furnaces developed to smelt the other metals could not produce zinc. Small quantities of metallic zinc can sometimes be found in the flues of lead blast furnaces.

Overview
History
The Charaka Samhita, thought to have been written between 300 and 500 AD, mentions a metal which, when oxidized, produces pushpanjan, thought to be zinc oxide. Zinc mines at Zawar, near Udaipur in India, have been active since the Mauryan period (c. 322 and 187 BCE). The smelting of metallic zinc here, however, appears to have begun around the 12th century AD. One estimate is t…
Characteristics
Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. T…
Compounds and chemistry
Zinc has an electron configuration of [Ar]3d 4s and is a member of the group 12 of the periodic table. It is a moderately reactive metal and strong reducing agent. The surface of the pure metal tarnishes quickly, eventually forming a protective passivating layer of the basic zinc carbonate, Zn 5(OH) 6(CO3) 2, by reaction with atmospheric carbon dioxide.
Production
Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper with an annual production of about 13 million tonnes. The world's largest zinc producer is Nyrstar, a merger of the Australian OZ Minerals and the Belgian Umicore. About 70% of the world's zinc originates from mining, while the remaining 30% comes from recycling secondary zinc. Commercially pure zinc i…
Applications
Major applications of zinc include (numbers are given for the US)
1. Galvanizing (55%)
2. Brass and bronze (16%)
3. Other alloys (21%)
4. Miscellaneous (8%)
Biological role
Zinc is an essential trace element for humans and other animals, for plants and for microorganisms. Zinc is required for the function of over 300 enzymes and 1000 transcription factors, and is stored and transferred in metallothioneins. It is the second most abundant trace metal in humans after iron and it is the only metal which appears in all enzyme classes.
Precautions
Although zinc is an essential requirement for good health, excess zinc can be harmful. Excessive absorption of zinc suppresses copper and iron absorption. The free zinc ion in solution is highly toxic to plants, invertebrates, and even vertebrate fish. The Free Ion Activity Model is well-established in the literature, and shows that just micromolar amounts of the free ion kills some organisms. A recent example showed 6 micromolar killing 93% of all Daphnia in water.
