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.

of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde ores is through the production of nickel matte after enriching the nickel content of the ore. This is com-
Nickel is primarily extracted from the nickel sulfides pentlandite, pyrrhotite, and millerite, which contain about 1% nickel content, and the iron-containing lateritic ores limonite and garnierite, which contain about 4% nickel content.
More nickel can be produced more efficiently from Australia's low-grade laterite ores if the metal is directly extracted after leaching with nitric acid, research suggests.
Copper-Nickel ores Pentlandite ((Ni,Fe)S) is the most important nickel sulphide mineral and is often associated with nickel-containing pyrrhotite and chalcopyrite. Gangue minerals can include talc and other troublesome silicates which must be dispersed and/or depressed.
The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

Laterite ores have three nickel-bearing layers, limonite, smectite and saprolite. Cobalt is also produced from Central African copper—cobalt ores. Platinum group metals are extracted from sulfide ores. Certain amount of nickel, cobalt and platinum group metals are produced from recycled end of …
Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits:
Most of the nickel we use on Earth is mined from a number of nickel ores: pentlandite and pyrrhotite (iron nickel sulfides, the two most important nickel ores), garnierite (hydrous nickel silicate), millerite (nickel sulfide), and niccolite (nickel arsenide).
The nickel ore is crushed to -5 inches in primary cone crushers, then reduced to -1/2" in short head cone crushers. The ore is then ground to -100 mesh in. ball mills. Using wet magnetic separators the magnetic ore is separated (pyrrhotite) and further reduced to -200 mesh in a ball mill.
Nickel sulphide ores generally have lower grades of nickel, but the nickel is easier and cheaper to extract. Also the ore is often founder deeper adding to costs of extraction.
Sulfide ores, containing copper, nickel, and iron minerals as distinct minerals, can be concentrated using mechanical means, such as magnetic separation and flotation. By contrast, the lateritic ores must be treated chemically to extract the nickel.

Extraction. Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.
