nickel production methods from pentlandite oxide ores

extraction of nickel from pentlandite ore

Main ore is Pentlandite; Nickel is extracted from ores through the Mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel.

nickel nickel production methods from pentlandite o ide ores

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).

Pentlandite - an overview ScienceDirect Topics

3.3.1 Nickel extraction process and nickel slag formation 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.

Nickel processing - Extraction and refining Britannica

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

The main source of the world's nickel is from copper-nickel sulphide ores with those mined at Sudbury, Ontario being by far the most extensive. The principle nickel sulphide is pentlandite (NiFeS2), which is usually associated with chalcopyrite and iron sulphides. International Nickel (INCO) and Sherritt Gordon use a bulk Cu/Ni float pictured below, followed by selective flotation of the two ...
