Zinc Cycling Through Nature
By natural erosion processes, a small part of the zinc in soil, rock and sediment is constantly moved and transported through the environment. Rain, snow, ice, solar heat and wind erode zinc-containing rocks and soil. Wind and water carry minute amounts of zinc to lakes, rivers and the sea, where it collects as sediment or is transported further. Natural phenomena such as volcanic eruptions, forest fires, dust storms and sea spray also contribute to the continuous cycling of zinc through nature. It is estimated that these natural emissions of zinc amount to 5.9 million metric tonnes each year.
Human activities do not add to the overall zinc amount on a global scale. But mining, production of goods and the use of zinc create situations where emissions to the atmosphere, soil and water can occur. These are known as anthropogenic emissions, which are estimated to be a fraction of the total emissions from the natural cycling of zinc from erosion, sea spray, volcanic eruptions etc.
Potential sources of anthropogenic zinc emissions include: the production and processing of zinc into products; emissions from power plants and other municipal and industrial sources not related to the zinc industry and; certain zinc applications where corrosion or abrasion may result in small releases of zinc to the environment, although these are generally widely dispersive in nature.
On a global scale, the influence of natural zinc cycling processes on environmental zinc levels is much more important than the influence from human activity. However, at a local scale, anthropogenic emissions can in some places outweigh natural processes.
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. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C. Above 210 °C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. 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 transition metalsaside from mercury and cadmium.
Many alloys contain zinc, including brass. Other metals long known to form binary alloys with zinc are aluminium, antimony,bismuth, gold, iron, lead, mercury, silver, tin, magnesium, cobalt, nickel, tellurium, and sodium. Although neither zinc norzirconium are ferromagnetic, their alloy ZrZn
2 exhibits ferromagnetism below 35 K.
A bar of zinc generates a characteristic sound when bent, similar to tin cry.
