Nickel is a hard silver-white metal with a high melting point and can withstand very low temperatures. Nickel is rarely found in the earth in its pure form; it mixes well with other metals to make many useful alloys. Nickel is malleable and ductile (can be beaten and drawn out into a wire) and is rust-resistant.

Nickel is extracted from ores via the Mond process, in which nickel oxides are purified through multiple steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel. This impure nickel then reacts with the carbon monoxide, becoming nickel tetracarbonyl.

Nickel is leached from laterite ores and precipitated as a sulfide. The objectives of the leaching stage are to extract the nickel and cobalt into solution, to oxidize the cobalt so that it is present as cobaltic hexamine. The filtrate is sent to ammonia stripping while the solids are sent to the cobalt circuit.

Pentlandite is mined in Canada, Russia, Australia and South Africa. Canada alone produces about 30 % of the world's sulfide nickel. Nickel is a common component of metal rich asteroids and meteoroids. Nickel, along with iron, is thought to make up the majority of the Earth's and other rocky planet's cores.

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Nickel smelting Molten ore being poured during the smelting of nickel The most important nickel ores are pentlandite and pyrrhotite, which usually contain nickel sulphide mixed with impurities such as copper The ore is smelted in a blast furnace to remove most of the impurities before being specially treated to separate the nickel and copper

Pentlandite is both an individual mineral, and the name of a mineral group. The Pentlandite group is composed of rare sulfides that have similar chemical structures, with Pentlandite being the most prominent member of the group. Pentlandite is named in honor of Joseph Barclay Pentland (1797–1873), a natural scientist from Ireland who first identified this mineral.
