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 …
The Nickel Disc is a product of the carbonyl refining process. This process makes one of the purest forms of nickel.

Nickel is a strategic metal with a wide range of industrial and metallurgical uses (Sadat et al., 2016).The use of nickel has now spread to a wide range of sectors, including steel alloying elements, space applications, and rechargeable batteries (Buyukakinci, 2008).Nickel is highly corrosion-resistant in contact with air, seawater, and organic 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 …
Due to the growing market of Electric Vehicles (EVs), there is a rise in battery demand. Nickel can be used as a potential element in cathode for lithium-ion batteries. Nickel can provide thermal stability, high energy density, and conductivity in cathodes of lithium-ion batteries. Low-grade chromite overburden from Sukinda mines …
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.
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 Thanh Hoa province, large chromite ore deposits were discovered. These types of ores also contain significant quantity of nickel metal, with total nickel reserves estimated to be over three million tones. According to the practices of mining and beneficiation of these chromite ores, nickel is discarded in the waste dumps as a non …
In anticipation of future demands, a comprehensive understanding of the chemical and mineralogical characteristics of nickel-bearing minerals is a prerequisite to devising effective nickel beneficiation methods.
