Nickel (Ni) is a chemical element with the atomic number 28, and it is a silvery white metal. Nickel was named after "Old Nick", a mischievous sprite from German Mythology; miners found an ore resembling copper but when they were unable to obtain any copper from it, they blamed Old Nick for plaguing the stone and named it Kupfernickel.. Have you ever …
It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., (1961) and …
Nickel, a valued metal, mainly exists as nickel oxide in laterite nickel ore. Furthermore, a large part of the laterite nickel ore is low-grade saprolitic ore. In this paper, a research on preparing ferro-nickel alloy from low-grade saprolitic laterite nickel ore using metallized reduction-magnetic separation was studied. In the research, the …

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into …

In 1899 Ludwig Mond developed a process for extracting and purifying nickel. The so-called "Mond Process" involves the conversion of nickel oxides to pure nickel metal. The oxide is obtained from nickel ores by a series of treatments including concentration, roasting and smelting of the minerals.
Nickel extraction from primary resources such as ores/minerals (sulfides, arsenides, silicates, and oxides) including the unconventional one viz., the polymetallic sea nodules, and various...
Nickel Sulfide ore is carried out by a flotation process which initially has a grade of 1-2% to concentrate with a grade of 6-20% (Ardra, 2019). For nickel oxide ore, a magnetic separator process is carried out to remove impurity (non-magnetic) minerals from the ore which initially had a grade of 0.8-1.5% to 20-30% (Nurjaman F, 2020).

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.
In particular, Fe and Ni content in roasted products, magnetic and non-magnetic products were chemically analysed by chemical titration, and the detail method as seen in reference [35]. 2.2.2.
