The nickel matte is further processed with the Sherritt-Gordon process. Nickel is preeminently an alloy metal, and its chief use is in nickel steels and nickel cast irons, in which it typically increases the tensile strength, toughness, and elastic limit. For kamacite, the alloy is usually in the proportion of 90:10 to 95:5, although impurities (such as cobalt or carbon) may be present, while for taenite the nickel content is between 20% and 65%. Nickel - Affinity - Electronegativity - Ionization Energy. Exposure to nickel metal and soluble compounds should not exceed 1 mg/M 3 (8 hour time-weighted average for a 40 hour week). Because it is resistant to corrosion, nickel was occasionally used as a substitute for decorative silver. Nickel is obtained through extractive metallurgy: it is extracted from the ore by conventional roasting and reduction processes that yield a metal of greater than 75% purity. Therefore, the abundance of 60Ni present in extraterrestrial material may provide insight into the origin of the solar system and its early history. Approximately 60% is in laterites and 40% is in sulfide deposits. Nickelocene is known; it has an electron count of 20, making it relatively unstable.  Relatively large amounts of nickel – comparable to the estimated average ingestion above – leach into food cooked in stainless steel. You can find it as symbol “Ag” on the periodic table.  Other nickel-bearing enzymes include a rare bacterial class of superoxide dismutase and glyoxalase I enzymes in bacteria and several parasitic eukaryotic trypanosomal parasites (in higher organisms, including yeast and mammals, this enzyme contains divalent Zn2+). Ni(III) can be stabilized by σ-donor ligands such as thiols and phosphines. Nickel is slowly oxidized by air at room temperature and is considered corrosion-resistant.   Its binding energy is greater than both 56Fe and 58Fe, more abundant elements often incorrectly cited as having the most tightly bound nuclides.
