The Advance Group iron and steel sector is a fundamental building block for many activities, providing a key material for construction, infrastructure, resource developments and other manufacturing, including the automotive industry. The industry also plays a major role in recycling steel..
Nickel is a Chemical Element.
Silvery white, tough, and harder than iron, nickel is widely familiar because of its use in coinage but is more important either as the pure metal or in the form of alloys for its many domestic and industrial applications. Elemental nickel very sparingly occurs together with iron in terrestrial and meteoric deposits. The metal was isolated (1751) by a Swedish chemist and mineralogist, Baron Axel Fredrik Cronstedt, who prepared an impure sample from an ore containing niccolite (nickel arsenide). Earlier, an ore of this same type was called Kupfernickel after “Old Nick” and his mischievous gnomes because, though it resembled copper ore, it yielded a brittle, unfamiliar metal. Twice as abundant as copper, nickel constitutes about 0.007 percent of Earth’s crust; it is a fairly common constituent of igneous rocks, though singularly few deposits qualify in concentration, size, and accessibility for commercial interest. The central regions of Earth are believed to contain considerable quantities. The most important sources are pentlandite, found with nickel-bearing pyrrhotite, of which certain varieties contain 3 to 5 percent nickel, and chalcopyrite, and nickel-bearing laterites, such as garnierite, a magnesium–nickel silicate of variable composition.
