Annabergite is isostructural with erythrite; both minerals are hydrous arsenates and differ only according to whether they contain cobalt or nickel. Annabergite is a secondary mineral derived from nickel arsenides such as niccolite (NiAs). Nickel, like cobalt, is a chromophore: due to its presence, annabergite is light green in color.

Nickel is sometimes found free in nature but is more commonly found in ores. The bulk of mined nickel comes from laterite and magmatic sulfide ores. The name originates from the German word kupfernickel, which means "false copper" from the illusory copper color of the ore.

Nickeline (Nickel Arsenide) - Amethyst Galleries

Nickeline has somewhat of an identity crisis. It is alternatively known as niccolite (mostly in Europe). Reference books often use Nickeline (Niccolite) or Niccolite (Nickeline) as a heading. The growing trend and "official" name is nickeline as is used here. Its first name was the German term "Kupfer nickel" or copper nickel. It sounds like ...

Copper Nickel Arsenides Mohawk, Mi

Sealed silica tube studies in the system Cu-Ni-As at 510±5°C show negligible solubility of copper in the nickel arsenides and nickel in the copper arsenides. All examples encountered in the Mohawk disequilibrium assemblage appear to involve essentially no (Cu,Ni) solid solubility among the binary arsenide compounds.

Sep 06, 2019· This is then reduced with carbon to obtain nickel metal. The nickel is purified by combining carbon monoxide with impure nickel at 50°C and atmospheric pressure, or from the mixture of nickel and copper, under more complex conditions, obtaining Ni(CO) 4, which is volatile. By thermal decomposition at 200°C, pure nickel is recovered at high ...

Nickel - Periodic table

Nickel is ferromagnetic and is a fair conductor of heat and electricity. Most nickel compounds are blue or green. Uses of Nickel. The majority of nickel is used in corrosion-resistant alloys, such as stainless steel. Tubing made from a copper-nickel alloy is used in desalination plants.

Copper Nickel Alloy Nanopowder detailed Analysis XRD TEM

Dr. Huojin Chan, (University of Science and Technology of China, Hefei, Anhui, China) Nanoshel nanoalloys with well-defined, controllable properties and structures on the nanometer scale coupled with the flexibility afforded by intermetallic materials has generated interest in bimetallic and trimetallic nanoclusters, which will be referred to as alloy nanoclusters or nanoalloys.

Assaying Nickel Determination Methods

Nickel is the commoner of the two, and is met with in commerce alloyed with copper and zinc as German silver; as also in the coinage of the United States and on the Continent. It is used for plating polished iron and steel goods, forming a coating little liable to rust and taking a good polish. The ores of nickel are not very common.

Arsenide - Wikipedia

The arsenides of the transition metals are mainly of interest because they contaminate sulfidic ores of commercial interest. The extraction of the metals – nickel, iron, cobalt, copper – entails chemical processes such as smelting that poses environmental risks. In the mineral, arsenic is immobile and poses no environmental risk.

Paul Brandes - Geology of the Keweenaw Peninsula, Michigan

Most of the native copper also carried a small amount (less than 0.5 percent) of arsenic and silver (Broderick, 1929). Copper nickel arsenides are also present occurring in veins in a flow top near Mohawk, the type locality for Mohawkite (now referred to as Domeykite) (Stoiber and Davidson, 1959).
