There are zinc mines throughout the world, with the largest producers being Australia, Canada, China, Peru and the U.S.A. Mines in Europe include Vieille Montagne in Belgium, Tara in Ireland, and Zinkgruvan in Sweden. Zinc metal is produced using extractive metallurgy. Zinc sulfide (sphalerite) minerals are concentrated using the froth flotation method and then usually roasted using pyrometallurgy to oxidise the zinc sulfide to zinc oxide. The zinc oxide is leached in sulfuric acid and the resulting solution is purified using zinc dust. The metal is then extracted by electrowinning as cathodic deposits. Zinc cathodes can be ...

Zinc acetate is a preparation of zinc used as a dietary supplement and in lozenges used to treat the common cold. It is often used to treat zinc deficiencies, for instance Wilson's disease. Industrial applications include wood preserving, manufacturing other zinc salts, polymer cross-linking, making ethylene acetate, and as a dye mordant and analytical reagent. Zinc acetate can also be used as a precursor in sol-gel chemistry for the preparation of zinc oxide, a commonly used transparent semiconductor. ...

Zinc sulfate (ZnSO4) is a clear, crystalline, water soluble chemical compound. The hydrated form, ZnSO4·7H2O, the mineral goslarite, was historically known as "white vitriol" and can be prepared by reacting zinc with sulfuric acid. It is used to supply zinc in animal feeds, fertilizers, and agricultural sprays; in making lithopone; in coagulation baths for rayon; in electrolytes for zinc plating; as a mordant in dyeing; as a preservative for skins and leather; and in medicine as an astringent and emet

Vegetarians and vegans seem not to suffer from zinc deficiencies any more than meat-eaters (source: Freeland-Graves JH, Bodzy PW, Epright MA. Zinc status of vegetarians. J Am Diet Assoc. 1980;77:655-661). However, phylate in many whole-grains and fiber in many foods may interfere with zinc absorption. Zinc is essential for building many enzymes, protein synthesis, reproductive health, immune system, speeds healing as a topical application, and may be an anti-oxidant. Plant sources of zinc include cooked dried beans, sea vegetables, fortified cereals, soyfoods, nuts, peas, and seeds. High doses ...

Zinc gluconate is the salt of gluconate and zinc II. It is an ionic compound consisting of two moles of gluconate for each mole of zinc. Zinc gluconate is a popular form for the delivery of zinc as a dietary supplement. It is found naturally, and can easily be manufactured using a fermentation process. In its pure form, it is a white to off-white powder. Zinc gluconate may interfere with the abso ...

Zinc pyrithione (abbreviated ZnP and also known as pyrithione zinc) is an antifungal agent best known for its use in treating dandruff and seborrheic dermatitis. It also has antibacterial properties and is effective against many pathogens from the streptococcus and staphylococcus class. Other medical uses involve treatment of psoriasis, eczema, ringworm, fungus, athletes foot ...

Zinc oxide is a chemical compound with formula ZnO. It is nearly insoluble in water but soluble in acids or alkalis. It occurs as white hexagonal crystals or a white powder commonly known as zinc white. It remains white when exposed to hydrogen sulfide or ultraviolet light. Crystalline zinc oxide exhibits the piezoelectric effect, is luminescent (it will change colour from white to yellow when heated, and back again when cooled down), and is light sensitive. Zinc oxide occurs in nature as the mineral zincite. Zinc peroxide, ZnO2 .½ H2O, is a whi ...

Zinc chloride (ZnCl2) is a colorless or white compound of zinc and chlorine that is extremely hygroscopic. Four crystalline structures have been reported, although in pure form (i.e. water-free) only the delta (hexagonal close-packed) phase can form. It can be quenched from the melt to form a glassy material. Concentrated aqueous solutions of zinc chloride have the interesting property of dissolving starch, silk and cellulose, so that solution ...

Zinc sulfide (or zinc sulphide) is a chemical compound with the formula ZnS. Zinc sulfide is a white to yellow colored powder or crystal. It is typically encountered in the more stable sphalerite crystal structure, although the wurtzite form is also known. Both of these forms are intrinsic semiconductors with a band gap of 3.68 eV at 300 K. It has a standard enthalpy of formation of -204.6 kJ/mol at 298 K. ...

Cadmium zinc telluride, (CdZnTe) or CZT, is (as the name indicates) a compound of cadmium, zinc and tellurium or more strictly speaking, an alloy of cadmium telluride and zinc telluride. A wide, direct bandgap semiconductor, it is used in a variety of applications, including radiation detectors, photorefractive gratings, electro-optic modulators and terahertz generation and detection. Radiation detectors using CZT can operate at room temperature, unlike some other materials (particularly germanium) which require liquid n ...

The Berne zinc tablet (also Gobannus tablet) was found in the 1980s in Berne. It is inscribed with an apparently Gaulish inscription, consisting of the four words, each on its own line, the letter formed by little dots impressed onto the metal: ΔΟΒΝΟΡΗΔΟ ΓΟΒΑΝΟ ΒΡΕΝΟΔΩΡ ΝΑΝΤΑΡΩΡ The dedication is to Gobannus, a Gallo-Roman god, the name originally simply meaning "the Smith". Brenodor is probably a placename, Brenno-duro- "town of Brennus, c.f. Salodurum > Solothurn, Vitudurum > Winterthur, Gaulish ...

Brass is an alloy of copper and zinc (a copper alloy), a solid solution. Typically it is more than 50 % copper. Some types of brass are called bronzes, despite their high zinc content. Brass is a versatile manufacturing material because of its hardness and workability. Admiralty brass contains 30% zinc and 1% tin which inhibits dezincification. Alpha brasses, with less than 35% zinc, are malleable, can be worked cold, and are used in pressing, forging, or similar. They contain only one ...

Vegetarian nutrition is a subject of importance to both vegetarians and dietitians. According to the American Dietetic Association (ADA), American Heart Association, National Institutes of Health, British Medical Association and the Mayo Clinic, vegetarian diets offer a number of health benefits compared to non-vegetarian diets. As an example, vegetarians tend to have lower body mass indices, lower levels of cholesterol, lower blood pressure, and less incidence of heart disease, hypertension, some forms of cancer, type 2 diabetes, renal disease, osteoporosis, dementias such as Alzheime ...

Calamine is an archaic name for an ore of zinc. The name was derived from the Belgian town of Kelmis, whose French name is "La Calamine", which is home to a zinc mine. During the late 18th century it was discovered that what had been thought to be one ore was actually two distinct minerals: zinc carbonate ZnCO3 or smithsonite and zinc silicate Zn4Si2O7(OH) ...

Bronze is the ancient name for a broad range of alloys of copper, but usually with tin as the main additive. First used in the Bronze Age, it made tools, weapons and armor harder or more durable than their stone and copper predecessors. In early use, the impurity arsenic made the alloy even harder. The earliest bronzes date to the late 4th millennium BC in Susa (Iran) and some ancient sit ...

In chemistry, an amphoteric substance is one that can react as either an acid or base (more generally, the word describes something made of, or acting like, two components). Examples include amino acids, proteins, and water. Many metals, such as zinc, tin, aluminium, and beryllium, have amphoteric oxides. For example, zinc oxide (ZnO) reacts differently depending on the pH of the solution: < ...
