Nickel processing Extraction and refining Britannica

Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

Flotation studies on a nickel ore containing 4–5% pentlandite, 4–5% chalcopyrite and 30–35% pyrrhotite with seven synthesized N-arylhydroxamic acids revealed that N-phynylacetyl-N-(2,6- dimethylphenyl)

Nickel Chemistry

Nickel carbonyl is a colourless, volatile, liquid. It is soluble in alcohol, benzene, and nitric acid but only slightly soluble in water, and insoluble in dilute acids and alkalis. Upon heating or in contact with acid or acid fumes, nickel carbonyl emits toxic carbon monoxide gas, a property exploited in preparation of nickel metal.

Chapter 6.10 Nickel World Health Organization

There are two commercial classes of nickel ore, the sulfide ores (pentlandite and pyrrhotite) and the silicate-oxide. Most nickel is produced from the sulfide ores, and the two largest producers, Canada and the Russian Federation, account for 20–25% each of total annual production, which was 784.82 thousand tonnes in 1988 (5).

The Gravimetric Determination of Nickel

The Gravimetric Determination of Nickel INTRODUCTION Nickel(II) forms a precipitate with the organic compound dimethylglyoxime, C4H6(NOH)2. The formation of the red chelate occurs quantitatively in a solution in which the pH is buffered in the range of 5 to 9. The chelation reaction that occurs is illustrated below.

Nickel Statistics and Information USGS.gov

Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits:

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.


12.2 General Guidance for Sample Preparation . Some general considerations during sample preparation are to minimize sample losses and to prevent contamination. Possible mechanisms for sample loss during preparation steps are discussed in Section 12.2.1, and the contamination of samples from sources in the laboratory is discussed in Section 12.2.2.
