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. in many stainless steel applications, 75% pure nickel can be used without further purification, depending on the impurities.
traditionally, most sulfide ores have been processed using pyrometallurgical techniques to produce a matte for further refining. recent advances in hydrometallurgical techniquesresulted in significantly purer metallic nicke · text under ccbysa licenseplating the role of nickel nickel institutein electroless nickel plating, a nickel coating is deposited on a surface using a controlled chemical process, or reduction, which is not based on an applied current. this is why electroless nickelnickel / cobalt mining extraction procedures in general, nickel is obtained by roasting nickel sulphides in air to obtain nio. this is then reduced with carbon to obtain nickel metal. the nickel is purified by combining carbon monoxide with impure nickel at 50°c and
