Arsenopyrite Uses and Benefits. Arsenopyrite is a sulfide mineral that contains arsenic and sulfur. It has a silver-white to pale yellow color and a metallic luster. It is often found in metamorphic and hydrothermal …
The arsenopyrite in the Cornish mines is important not so much as a sulfide, but for the secondary species it fathered. Weathering of Cornish arsenopyrite produced some of the world's finest examples of liroconite, olivenite, clinoclase and chacophyllite, all secondary arsenic species. Of these four, liroconite, a fairly complex hydrous ...

Arsenopyrite — Portugal. Origin: Panasqueira Mines, Covilha, Castelo Branco, Portugal Number: (5002985) Size: 5.7 x 5.0 x 1.6 cm (miniature)
Attractive combination specimen with a grouping of calcite crystals to 2.7 cm across on one side of this sulfide matrix. Blocky lustrous metallic crystals of arsenopyrite measuring to 1.3 cm are scattered throughout, as well as crystallized pyrite, sphalerite, and rhodochrosite. This is in terrific condition.
Arsenopyrite is commonly present in mining tailings and, together with pyrite, is responsible for acid rock drainage (ARD) phenomenon. The mineral undergoes oxidation in contact with oxygen and water producing a solution containing acid and heavy metals and, hence, causing important environmental impacts. Density functional/plane …
The form and location of gold in the structure of arsenopyrite and pyrite minerals, and the mechanisms for the mobility agglomeration of gold in arsenopyrite during thermal treatment, have been studied using a combination of Rietveld X-ray diffraction refinement, Convergent Beam Electron Diffraction (CBED) and Atomic Location by Channelling …
Arsenopyrite is formed in hydrothermal deposits, especially those formed at medium to high temperatures. It is often associated with other sulfides such as pyrite and chalcopyrite. CLARK COUNTY: Reported from an unspecified locality in the county as particles in a quartz veins that also yielded some silver and gold values when assayed (Irving, 1882). …
Gold in Arsenopyrite. As case study for the processing of an ore with a refractory component of visible and invisible Gold associated in and with Arsenopyrite had a gold content in the feed ranged from about 1.0 g/tonne to about 8.7 g/tonne depending on lithology. There was some difficulty in measuring the feed gold content due to the …
Arsenopyrite (IMA symbol: Apy) is an iron arsenic sulfide (FeAsS). It is a hard (Mohs 5.5-6) metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1. When dissolved in nitric acid, it releases elemental sulfur. When arsenopyrite is heated, it produces sulfur and arsenic vapor. With 46% arsenic content, arsenopyrite, along with …

Arsenopyrite is an important ore of the element arsenic. It is also a minor ore of gold, as it contains traces of gold in some localities. Well-formed, lustrous Arsenopyrite crytals are important collector specimens. Arsenopyrite can be found worldwide, but crystals of good quality are more limited.

Pyrite as an Ore of Gold. The most important use of pyrite is as an ore of gold. Gold and pyrite form under similar conditions and occur together in the same rocks. In some deposits small amounts of gold occur as inclusions and substitutions within pyrite. Some pyrites can contain 0.25% gold by weight or more.
