1. Introduction. Nickel is an important strategic metal produced at over 2 million tonnes annually [1].Approximately 60% of all Ni is consumed in the production of stainless steel [2, 3].Currently, Ni is primarily extracted from two types of ores: laterites and sulfides [[4], [5], [6], [7]].Although sulfide ores account for a smaller fraction of global Ni …

A chemist is tasked with determining the concentration of nickel in a water sample drawn from a well next to a nickel mine. To analyze the sample using atomic absorbance spectroscopy (AAS), she prepares six samples (0-5) by adding 10.00 mL of well water to six 50.00-ml volumetric flasks. She then adds increasing volumes of 25.00-ppm nickel ...

Question: An nickel ore sample is found to be 43.55 % nickel by mass. [a] grams of ore are needed to obtain 500.0 g of nickel. An nickel ore sample is found to be 43.55 % nickel by mass. [a] grams of ore are needed to obtain 500.0 g …
Sulfation roasting, a common activation technique, is a potential method for cleaner production of nickel from complex low-grade ores. In this study, nickel oxide–sulfide mixed ore concentrate was roasted with the addition of ammonium sulfate under a static air atmosphere, and the roasted products were leached by water, in order to evaluate the …
This article examines contemporary routine and umpire quality methods for the analysis of nickel ores, nickel metal and nickel alloys. Sample preparation and sampling are also discussed, but the emphasis is on sample preparation and analysis, since sampling is all too often done by people not part of the analytical laboratory.
Nickel, chemical element, ferromagnetic metal of Group 10 (VIIIb) of the periodic table, markedly resistant to oxidation and corrosion. Silvery white, tough, and harder than iron, nickel is widely familiar because of its use in coinage but is more important as the pure metal or in the form of alloys.
Nickel and its compounds have no characteristic odor or taste. Ni compounds are used for Ni plating, to color ceramics, to make some batteries, and as catalysts that increase the rate of chemical reactions. One of the most toxic nickel compounds is nickel carbonyl, Ni(CO)4, which is used as a catalyst in petroleum refining and in the plastics ...
