Environmental Fate of Zinc
Zinc released to the environment follows a cycle (figure 1) in which zinc from mineral ore bodies is converted through extraction and refining processes from its mineral state (mostly sphalerite ore, zinc sulfide) into the metallic state. Most of this metal will have a long service in stable metal applications and will be recovered and recycled at the end of life. Metallic zinc that is exposed to the atmosphere may be subject to corrosion that will result in a slow release of small amounts of zinc into the environment.
Zinc metal is also transformed into zinc compounds (e.g. zinc oxide, zinc chloride, zinc phosphate) that are used in a wide variety of applications. These uses may also result in small diffusive releases.
During the production and use phase of zinc, zinc compounds with varying solubility may be formed and be released into the environment. In addition to these emissions related to human activity, a natural flow of zinc will always cycle through the environment due to the natural processes of weathering and erosion. All these processes mobilize a variety of zinc compounds into the environment.
Once mobilized, zinc interacts with the different components of water, sediments and soil and ultimately partitions between different fractions in these environmental compartments. This interaction and the dynamic processes involved ultimately define zinc’s environmental fate, i.e. the form(s) in which the metal will be present in the environment and in which it will ultimately end up. In this respect, most of the zinc will return to the stable chemical form, often ZnS, from which it was originally mined. This “mineralization” back into stable chemical forms closes the “cycle.”
The original and ultimate chemical forms of zinc (mainly ZnS) are very stable, and the contained zinc has very low solubility and very low potential for uptake by organisms (bioavailability).
Zamak 7 has less magnesium than zamak 3 to increase fluidity and ductility, which is especially useful when casting thin wall components. In order to reduce inter-granular corrosion a small amount of nickel is added and impurities are more strictly controlled.
