Zinc

OverviewCharacteristicsCompounds and chemistryHistoryProductionApplicationsBiological rolePrecautions

Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue silvery appearance when oxidation is removed. It is the first element in group 12 of the periodic table. In some respects, zinc is chemically similar to magnesium both elements exhibit only one normal oxidation state (+2), and the Zn and Mg ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite(zi

Environmental Impacts of Mining and Smelting

The mining sector is responsible for some of the largest releases of heavy metals into the environment of any industry. It also releases other air pollutants including sulfur dioxide and nitrogen oxides in addition to leaving behind tons of waste tailings, slag, and acid drainage.

Soil texture and water content can be greatly modified in disturbed sites, leading to plants community changes in the area. Most of the plants have a low concentration tolerance for metals in the soil, but sensitivity differs among species. Grass diversity and total coverage is less affected by high contaminant concentration than forbs and shrubs. Mine waste materials rejects or traces due to mining activity can be found in the vicinity of the mine, sometimes far away from the source. Established plants cannot move

Air PollutionWater PollutionDamage to LandLoss of BiodiversityAir quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining. Wind erosion and nearby vehicular traffic cause such materials to become airborne. Lead, arsenic, cadmium, and other toxic elements are often present in such particles. These pollutants can damage the health of people living near the mining site.

Metals in Medicine and the Environment

Environmental issues have been caused by mining in both ancient and modern times. Acid mine drainage (AMD, Figure 2, Refs 7,8) is caused when metal sulfides in the underground ore are exposed to the natural elements. The sulfides are oxidized and the products released are sulfuric acid and free heavy metals which contaminate the surrounding areas. AMD has had a huge negative impact on the
