One-Step Extraction of Nickel from Nickel Sulfide
The conventional nickel smelting and refining is the dominant strategy for nickel production from the sulfide nickel ores. The main disadvantages are the significant amount of SO 2 emissions during smelting and complex refining processes. In this paper, the authors investigated a solid-state nickel extraction method that recovered nickel values into ferronickel …
Nickel
The name nickel originates from the German term "Kupfernickel," which means devil's copper. It is more probably to be found in the Earth's core rather than the Earth's crust. This element is amongst the most versatile natural substances extracted on the planet. Nickel's chemical name is Ni; thus, the metal is also called Ni element.

The removal of nickel from aqueous solutions was investigated using water washed raw leaves of Ricinus communis (RLRC). The adsorbent was characterized by Fourier Transform infrared spectroscope (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM) with an EDAX (energy dispersive analysis of X-ray), and zeta potential measurements will be carried out in …
Nickel (Ni)
For commercial purposes, the nickel carbonyl process is used to purify nickel extracted from nickel ores, such as laterites and magmatic sulfide deposits. Since nickel mainly occurs in Earth's iron-nickel core, it's relatively inaccessible. The organic substances that also occur in the deeper layer of Earth, such as oil and coal, absorb ...
