Cobalt (Co) is a hard, gray metal that occurs naturally. It is found in rocks, soil, water, plants, and animals, including people. It can harm the eyes, skin, heart, and lungs. Exposure to cobalt may cause cancer. Workers may be harmed from exposure to cobalt and cobalt-containing products.
In the mining cohorts and often in industrial cohorts in general, the prevalence of smoking is greater than in the general population. Therefore, tobacco smoking which is a known risk factor for lung cancer may act as a confounder of the relationship between the particular type of mining or mining exposures and lung cancer.
Nickel and cobalt are mostly used in alloys, e.g., stainless steels and aerospace alloys. Each has many other uses. Recycling is accomplished by prior identification and return of alloy scrap. 2010 world mine productions of nickel and cobalt were approximately 1,500,000 and 60,000 tons, respectively . 2.2.3.
Cobalt-60, a radioactive isotope of cobalt, is an important source of gamma rays and is used to treat some forms of cancer and as a medical tracer. Cobalt-60 has a half-life of 5.27 years and decays into nickel-60 through beta decay. Cobalt compounds have been used for centuries to color porcelain, glass, pottery, tile and enamel.
Cobalt-60. Cobalt-60 (60 Co) has been used for radiotherapy cancer treatment, food irradiation and industrial applications. As cobalt-60 decays into a stable nickel-60 isotope, two wavelengths of high-energy gamma-rays are emitted (1.17 and 1.33 MeV- average of 1.25 MeV used).

Cobalt processing: Cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close-packed crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face-centred cubic. The metal has 12
· Cobalt represents a by-product of nickel and copper mining, and the metal appears naturally in rocks and dirt. Compounds of cobalt give ceramic glass a deep blue color, and give rich tints to glazes. After the isotope cobalt-60 was identified, it became valuable as an alloy because it resists corrosion and adds strength to other metals. This ...
· Cobalt is a naturally occurring element that does have beneficial applications. For instance, cobalt is an essential component of vitamin B-12. Cobalt has been added to pigments to produce a distinct blue color. Lithium-ion batteries contain cobalt. In the medical field, cobalt-60 is used in radiotherapy and for sterilizing medical equipment.
· The mining and processing of nickel-rich ores can generate high loadings of dust in the air, that contains high concentrations of potentially toxic metals, including nickel itself, copper, cobalt ...
Cobalt is a byproduct of the production of other metals like nickel and copper, but it also exists in the earth's crust on its own, in mines primarily in the Democratic Republic of the Congo.
Nickel refinery dust is a mixture of many nickel compounds, with nickel subsulfide being the major constituent. (3,4,6) Animal studies have also reported lung tumors from inhalation exposure to nickel refinery dusts and to nickel subsulfide. (3,4) EPA has classified nickel refinery dust and nickel subsulfide as Group A, human carcinogens. (3,4)
· Cobalt compounds have been used for centuries to colour porcelain, glass, pottery, tile and enamel. The isotope of cobalt, Cobalt-60, is used to treat some forms of cancer. The element is important to human nutrition as it is an essential part of vitamin B12. A cobalt mine averages three to five years from discovery to production.
· Nickel is a metal, commonly used to make coins, magnets, jewelry, stainless steel, electronics, and components of industrial machines. Most people are familiar with the attractive mirror-finish that can be achieved by nickel plating.
· The existing studies on cobalt, nickel and copper have focused on the biological distribution of these particles following exposure through the lungs, skin and GIT. The exact mechanisms of cobalt- and nickel-based nanoparticle-induced carcinogenesis in experimental animals are not clear.
Overview Information Nickel is a mineral. It is found in several foods including nuts, dried beans and peas, soybeans, grains, and chocolate.The body needs nickel, but in very small amounts.
