Production and use There are two commercial classes of nickel ore the sulfide ores (pentlandite and pyrrhotite) and the silicate-oxide. Most nickel is produced from the sulfide ores and the two largest producers Canada and the Russian Federation account for 20–25 each of total annual production which was 784.82 thousand tonnes in 1988 (5).
Nickel processing - Extraction and refining | …
Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag. This is done in a rotating converter of the type used in copper production. The slag is ...

Nickel: smelting, producing-Metalpedia
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.

A second advantage is that sulfide ores often contain important amounts of other values particularly copper cobalt platinum group metals and gold and silver and the established technology makes their recovery profitable In contrast the laterites cannot be significantly upgraded a tonne of ore is a tonne of feed to the extraction process
Pentlandite - an overview | ScienceDirect Topics
Primary nickel is produced from two very different ores: sulfide ores and laterite (oxide) ores. Sulfide ores, which are generally mined from underground and often found in conjunction with copper-bearing ores, contain copper–iron sulfides in association with nickel–iron sulfides. The principal sulfide mineral of nickel is …
Lateritic nickel ore deposits - Wikipedia
Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization. Two kinds of lateritic nickel ore ...

Lateritic ores, by contrast, are usually smelted by pyro-metallic methods because of their high iron content. Lateritic ores also have a high moisture content (35-40%) that requires drying in a rotary kiln furnace. It produces nickel oxide, which is then reduced using electric furnaces at temperatures between 2480-2930 F° (1360-1610 C°) and ...
NICKEL AND COBALT ORES: FLOTATION
ores is through the production of nickel matte after enriching the nickel content of the ore. This is com- monly carried out by magnetic separation, Sotation, or a combinationof both after the ore is comminuted to below 200 m in size. The enrichment depends upon the degree of rejection of the other sulRde and non-sulRde gangue. The maximum grade of nickel achieved by Sotation is around 28% Ni ...
