It is known that virtually all of the nickel in nickel sulfide ores occurs in the
mineral pentlandite [(Ni,Fe)9S8]. Therefore, pentlandite is the most common and
abundant ore for extraction of nickel, accounting for over 60% of nickel world
production [1, 2].
The pyrometallurgical extraction of nickel from its sulfide ores is very similar
to the copper extraction process from copper sulfide concentrates. In essence, iron
and sulfur are eliminated by selective oxidation and fluxing. In fact, the oxidation of
pentlandite is the most important chemical process in the pyrometallurgical route
[3].
Because of all mentioned, the characterization of the structural properties of
six pentlandite samples was carried out in this paper. The samples of pentlandite
were roasted in air atmosphere for 30min, in five different temperatures: 400, 500,
600, 700 and 800 °C. Investigation of structural properties and obtained oxidation
products was performed using X-ray diffraction (XRD), scann...ing electron microscopy
(SEM) and energy dispersive spectrometry (EDS).
