Such payments shall be made to small domestic producers of zinc as long as the market price for prime western zinc at East Saint Louis, Illinois, as determined by the Secretary, is below 14-1/2 cents per pound, and such payments shall be 55 per centum of the difference between 14-1/2 cents per pound and the average market price for the month in which the sale occurred as determined by the Secretary.

If working in a zinc mine, which he once did for 87-1/2 cents an hour, paid more than playing center field for the Yankees, Mantle would work in a zinc mine.

The Belgians were interested primarily in the economic development of the Congo, which is rich in copper, tin, cobalt, manganese, zinc, and uranium, and cotton and palm oil.

Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms.

The river's name may be attested to in the Gaulish ( Helvetic ) Berne zinc tablet which dates back to Roman Gaul.

As an example, an iron or steel ship's hull may be protected by a zinc sacrificial anode, which will dissolve into the seawater and prevent the hull from being corroded.

* Admiralty brass contains 30 % zinc, and 1 % tin which inhibits dezincification in many environments.

Red brass is also an alternative name for copper alloy C23000, which is composed of 14 – 16 % zinc, 0. 05 % iron and lead, and the remainder copper.

Although forms of brass have been in use since prehistory, its true nature as a copper-zinc alloy was not understood until the post medieval period because the zinc vapor which reacted with copper to make brass was not recognised as a metal.

It was eventually replaced by speltering, the direct alloying of copper and zinc metal which was introduced to Europe in the 16th century.

The compositions of these early " brass " objects are very variable and most have zinc contents of between 5 % and 15 % wt which is lower than in brass produced by cementation.

However the large number of copper-zinc alloys now known suggests that at least some were deliberately manufactured and many have zinc contents of more than 12 % wt which would have resulted in a distinctive golden color.

The 4th century BC writer Theopompus, quoted by Strabo, describes how heating earth from Andeira in Turkey produced " droplets of false silver ", probably metallic zinc, which could be used to turn copper into oreichalkos.

Brass was produced by the cementation process where copper and zinc ore are heated together until zinc vapor is produced which reacts with the copper.

They show no signs of slag or metal prills suggesting that zinc minerals were heated to produce zinc vapor which reacted with metallic copper in a solid state reaction.

The fabric of these crucibles is porous, probably designed to prevent a build up of pressure, and many have small holes in the lids which may be designed to release pressure or to add additional zinc minerals near the end of the process.

A number of Islamic writers and the 13th century Italian Marco Polo describe how this was obtained by sublimation from zinc ores and condensed onto clay or iron bars, archaeological examples of which have been identified at Kush in Iran.

In 10th century Yemen al-Hamdani described how spreading al-iglimiya, probably zinc oxide, onto the surface of molten copper produced tutiya vapor which then reacted with the metal.

German brass making crucibles are known from Dortmund dating to the 10th century AD and from Soest and Schwerte in Westphalia dating to around the 13th century confirm Theophilus ' account, as they are open-topped, although ceramic discs from Soest may have served as loose lids which may have been used to reduce zinc evaporation, and have slag on the interior resulting from a liquid process.

The crucible lids had small holes which were blocked with clay plugs near the end of the process presumably to maximise zinc absorption in the final stages.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That the Secretary of the Interior is hereby authorized and directed to establish and maintain a program of stabilization payments to small domestic producers of lead and zinc ores and concentrates in order to stabilize the mining of lead and zinc by small domestic producers on public, Indian, and other lands as provided in this Act.

Brass is an alloy made from copper and zinc.

Also, the power of the cell diminishes over time because the hydrogen gas is not released, accumulating instead on the surface of the zinc electrode and forming a barrier between the metal and the electrolyte solution.

As long as the zinc remains intact, the iron is protected from the effects of corrosion.

The resultant current ensures that the zinc coating is sacrificed but that the base iron does not corrode.

Owing to the complete absence of mountain building and glaciation since the Permian ( in many areas since the Cambrian ) ages, the outback is extremely rich in iron, aluminium, manganese and uranium ores, and also contains major deposits of gold, nickel, iron, lead and zinc ores.

Selenium and zinc are commonly referred to as antioxidant nutrients, but these chemical elements have no antioxidant action themselves and are instead required for the activity of some antioxidant enzymes, as is discussed below.

Brass is an alloy of copper and zinc ; the proportions of zinc and copper can be varied to create a range of brasses with varying properties.

* Prince's metal or Prince Rupert's metal is a type of alpha brass containing 75 % copper and 25 % zinc.

* Alpha-beta brass ( Muntz metal ), also called duplex brass, is 35 – 45 % zinc and is suited for hot working.

* Cartridge brass is a 30 % zinc brass with good cold working properties.

* Common brass, or rivet brass, is a 37 % zinc brass, cheap and standard for cold working.

An alloy of 95 % copper and 5 % zinc, gilding metal is typically used for ammunition bullet " jackets ", e. g. full metal jacket bullets.

* High brass contains 65 % copper and 35 % zinc, has a high tensile strength and is used for springs, screws, and rivets.

* Low brass is a copper-zinc alloy containing 20 % zinc with a light golden color and excellent ductility ; it is used for flexible metal hoses and metal bellows.

* Muntz metal is about 60 % copper, 40 % zinc and a trace of iron, used as a lining on boats.

* Naval brass, similar to admiralty brass, is 40 % zinc and 1 % tin.

Brass has higher malleability than bronze or zinc.

The mercury battery using zinc and mercuric oxide provided higher levels of power and capacity than the original dry cell for early electronic devices, but has been phased out of common use due to the danger of mercury pollution from discarded cells.

The most common decay mode of a radioisotope of zinc with mass number higher than 66 is beta decay ( β < sup >–</ sup >), which produces an isotope of gallium.

Aluminium anodes have several advantages, such as a lighter weight, and much higher capacity than zinc.

Robert experimented, believing he could jump higher if the zinc in batteries could somehow be charged with static electricity.

Animals given zinc or magnesium dosed in their drinking water had a significantly higher concentration of these elements in the serum than animals given the same elements in much higher amounts with food and provided with low-mineral water to drink.

The quantities of sodium, potassium, zinc, iron, copper, manganese, niacin and vitamin C were relatively higher than the amounts in cow's milk.

Korean bronzes contain a higher percentage of zinc than those of the neighboring bronze cultures.

Recent studies have demonstrated that the BAPTA moiety actually binds to zinc ions with a substantially higher affinity than calcium.

Mercury coated the interior of brass cases with smokeless powder loads, and the higher pressures of smokeless powder charges forced the mercury into grain boundaries between brass crystals where it formed zinc and copper amalgams weakening the case so it became unsuitable for reloading.

Compared with zinc-carbon batteries of the Leclanché or zinc chloride types, alkaline batteries have a higher energy density and longer shelf-life, with the same voltage.

It uses the same zinc anode and electrolyte as an alkaline battery, but its capacity is around 50 % higher.

In milk it is found in higher concentrations than would be possible at the normal pH because it exists in a colloidal form in micelles bound to casein protein with magnesium, zinc and citrate-collectively referred to as colloidal calcium phosphate ( CCP )

The higher mountain areas are forest and pasture and in places there is mining of copper, zinc, iron and other metals.

The use of a zinc ion in binding leads to a higher affinity interaction.

The electronegativity of copper is much higher than its neighbor in the group 12 elements, zinc, suggesting less nucleophilicity for carbon.

Liaoning bronzes contain a higher percentage of zinc than those of the neighboring bronze cultures.

The materials used to make bullets are: pure lead ; alloyed lead for hardness ; gilding metal jacket which is a copper alloy of nickel and zinc to promote higher velocities ; pure copper ; copper alloy of bronze with tungsten steel alloy inserts to promote weight.

Zinc dust is added to the clarified, de-aerated solution which precipitates the gold ; zinc having a higher affinity for the cyanide ion than gold.

While zinc alloys are popularly referred to as pot metal or white metal, zamak is held to higher industrial standards.

Manufacturers recommend storage of zinc – carbon batteries at room temperature ; storage at higher temperatures reduces the expected service life.

It prefers soil that is sandy, well-drained, and nutrient-rich, particularly with higher concentrations of boron, copper, iron, manganese, molybdenum, and zinc.
