	Nickeline (Nickel Arsenide)
		Nickeline's structure is fairly simple with the nickel ions, in hexagonal packing, forming stacked identical layers parallel to the major six-fold axis.
		The arsenic ions rest between the nickel ion layers, but in a staggered or alternating sequence such that the next layer is not in the same position as the previous layer.
		Nickeline is not exactly a common mineral, but is found with other nickel and cobalt sulfide ores and thus it is included with them when mined for their various ores.

	Nickel - LoveToKnow 1911
		It occurs in the uncombined condition and alloyed with iron in meteorites; as sulphide in millerite and nickel blende, as arsenide in niccolite and cloanthite, and frequently in combination with arsenic and antimony in the form of complex sulphides.
		Nickel is used for the manufacture of domestic utensils, for crucibles, coinage, plating, and for the preparation of various alloys, such as German silver, nickel steels such as invar (nickel, 35.
		Nickel sesquioxide, N1203, is formed when the nitrate is decomposed by heat at the lowest possible temperature, by a similar decomposition of the chlorate, or by fusing the chloride with potassium chlorate.

		Nickel is used as a protective and ornamental coating for less corrosion resistant metals, especially iron and steel; it is applied by electroplating and by other methods (see plating).
		Nickel occurs in a number of minerals; its chief ores are pentlandite and pyrrhotite (nickel-iron sulfides) and garnierite (nickel-magnesium silicate).
		Nickel sulfide ores are concentrated by the flotation process, then smelted or roasted to partially convert them to the oxide form, and further treated in a Bessemer converter to form a matte.

	Nickel (IARC Summary & Evaluation, Volume 49, 1990)
		Nickel and nickel compounds are absorbed from the respiratory tract, and to a smaller extent from the gastrointestinal tract, depending on dissolution and cellular uptake.
		Absorbed nickel is excreted predominantly in the urine.
		Nickel chloride and nickel nitrate were inactive in assays in vivo for induction of dominant lethal mutation and micronuclei, and nickel sulfate did not induce chromosomal aberrations in bone-marrow cells; however, nickel chloride induced chromosomal aberrations in Chinese hamster and mouse bone-marrow cells.

	Platinum - Wikipedia, the free encyclopedia
		A heavy, malleable, ductile, precious, grey-white transition metal, platinum is resistant to corrosion and occurs in some nickel and copper ores along with some native deposits.
		Platinum is often found free in areas of the Americas and alloyed with iridium as platiniridium.
		Platinum is produced commercially as a by-product of nickel ore processing in the Sudbury deposit.

		The primary objectives of this experiment were to establish the extent of solid solution of nickel in the copper arsenides and copper in the nickel arsenides, the possible existence of some ternary phase or phases and the fields of coexisting phases.
		, is the stable copper arsenide phase in the arsenic-rich portion of the diagram and coexists with arsenic pararammelsbergite and β-domeykite.
		An objection may be raised that the copper arsenides were in fact derived from the action of initially arsenic-poor fluids upon the nickel arsenide, and the adjoining copper in the wall rocks.

		Nickel matte is a substance produced as an intermediate in the production of nickel metal, included in Einecs and reported by Industry as a HPVC under the ESR.
		NiPERA has provided data for a different nickel arsenide with CAS Number 12255-80-0 (this substance is not included in the proposal) to show that no classification for acute toxicity would be required, and that the acute toxicity predicted on the basis of the water-solubility of the nickel component was correct.
		It was clear from our earlier discussions of nickel dinitrate (classification agreed in September 2004) that severe effects on eye irritation are seen with this compound that are not seen with other soluble nickel compounds reviewed, and it was suggested that this is related to the oxidising potential of the compound.

	Silver Batopilas, Mexico; Bullard's Peak, New Mexico
		Remnant crystals of the arsenides within polybasite and proustite indicate that the arsenides were deposited earlier in the sequence of mineralization.
		This association of arsenides with native silver appears to be so typical of those native silver ores which are generally recognized as being due to hypogene mineralization that a similar origin for this ore seems probable.
		The association of nickel and cobalt arsenides with native silver is becoming increasingly common as silver deposits are being studied in greater detail.

		I saw your writeup on "pumpernickel," and I was wondering whether "nickel" as in the type of coin is related to this.
		But the five-cent nickel is not the only coin that has been made of nickel, or called a "nickel." The original "nickel" was a one-cent piece issued from 1857 to 1864; a three-cent nickel was minted from 1866 to 1883; and the now-familiar five-cent nickel (having various designs) since 1883.

		It intersected a 25.8m wide zone (23m estimated true width) averaging 1.6% nickel, which is equated with the South Avebury North Lens deposit.
		The company says initial observation and assaying indicate that in excess of 95% of the nickel is present as coarse pentlandite (nickel sulphide) with only minor amounts of nicolite (nickel arsenide) near the hanging wall of the intersection.
