The metallurgy of nickel is complicated in its details, many of which vary widely, according to the particular ore being processed. In general, the ore is transformed to dinickel trisulfide, Ni 2 S 3 (with nickel in the +3 oxidation state), which is roasted in air to give nickel oxide, NiO (+2 state), which is then reduced with carbon to obtain the metal.

Within the channellized ore environment, elevated Ni and low Cr values are observed in the lower flow unit of the ultramafic pile (Fig. 4 a). Nickel concentrations exceed those of Cr, so the Ni : Cr ratio is >1. Higher in the ultramafic pile, Ni decreases as Cr increases. Download : Download full-size image; Fig. 4.

nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 °C (2,647 °F) and a ...

Nickel's discovery can be traced back to 1751 when Axel Fredrik Cronstedt isolated the metal from a copper ore that deceived miners, earning the name …

The main source of nickel has gradually become the recovery of ferronickel concentrate from low-grade laterite nickel ore. In this work, high-grade ferronickel concentrate was prepared by a reduction roasting-magnetic separation process, and low-grade ferronickel concentrate and CaF 2 were used as composite additives to promote …

History and Discovery. Nickel's discovery can be traced back to 1751 when Axel Fredrik Cronstedt isolated the metal from a copper ore that deceived miners, earning the name "kupfernickel" or "false copper.". The isolation of nickel marked a significant milestone in the field of chemistry and set the stage for its subsequent applications.
