How is nickel extracted?

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. read more

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. read more

Nickel dimethylglyoxime is an insoluble salt useful in analytical chemistry in precipitating nickel. Nickel carbonyl, Ni(CO) 4, a liquid at room temperature, is employed in the carbonyl nickel-refining process. Like all other carbonyls, it is poisonous. Nickel subsulfide, Ni 3 S 2, is the nickel component of matte involved in pyrometallurgy. read more

Most of the nickel on Earth is believed to be concentrated in the planet's core. Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel. About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel. read more
