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.

Even Champion was drawing on techniques dating back to the Middle Ages, however. Zinc was first used in China by at least A.D. 1637, and was mined and smelted in India even earlier — by the ninth century B.C., at least, according to the 2006 research published in the journal Ancient Asia. At first, ancient people used zinc ores mostly to make brass (an alloy of copper with zinc). However, zinc was recognized as a metal in its own right by 1374 in India, according to the International Zinc Association (IZA).
What is the atomic number of zinc?
This metal is positioned on the Periodic Table of the Elements with the atomic number of 30 , and was used by Greeks and Romans in ancient times, according to the Royal Society of Chemistry. But zinc was not as popular as copper or iron, according to a 2006 paper in the open-access journal Ancient Asia; it boils away at a lower temperature than is required to extract it from its ore, so ancient smelting techniques were not up to the task of isolating zinc.

Zinc may be the only known cure for the common cold — sort of. According to the NIH, medical studies have found that if zinc lozenges or spray are used within 24 hours of the onset of symptoms, the length of a cold is reduced.

How is zinc deposited in electrogalvanizing?
In electrogalvanizing, zinc is deposited on a steel strop in as many as 20 consecutive electrolytic coating cells. There are several successful cell designs; the simple vertical cell is discussed here to explain the principle. The strip, connected to the negative side of a direct current through large-diameter conductor rolls located above and between two cells, is dipped into a tank of electrolyte by a submerged sink roll. Partially submerged anodes, opposing the strip, are connected to the positive side of the electric current by heavy bus bars. Zinc cations (i.e., positively charged zinc atoms) present in the electrolyte are converted by the current into regular zinc atoms, which deposit on the strip. The bath is supplied with zinc cations either by zinc anodes, which are continuously dissolved by the direct current, or by zinc compounds continuously added to the electrolyte. In the latter case the anodes are made of insoluble materials, such as titanium coated with iridium oxide. The electrolyte is an acidic solution of zinc sulfide or zinc chloride with other bath additions to improve the quality of the coating and the current efficiency. Coating thickness is easier to control than in the hot-dip process because of the good relationship between electrical current and deposited zinc.
What is zinc coated steel?
Hot-dip galvanizing is the most common procedure for coating steel with zinc. This may be a batch process known as general galvanizing or a continuous coating of coils of steel strip. In general galvanizing, steel is pickled in acid, treated with fluxing agents, and then dipped in a bath of molten zinc at about 450 °C (840 °F). Layers of iron-zinc alloy are formed on the surface and are topped with an outer layer of zinc. Objects so treated range from small nuts and bolts to steel window frames and large girders used in construction. An ordinary grade of zinc containing up to 1.5 percent lead is normally used in this process.
What is galvanizing steel?
