About ArsenopyriteHide Named in 1847 by Ernst Friedrich Glocker for its composition, a contraction of the antiquated term "arsenical pyrite." Arsenopyrite was known much before 1847 and arsenopyrite, as a name, may be taken as a simple translation of "arsenkies". Well-formed crystals of arsenopyrite are most often found in pegmatites, marbles, and dolomites that have been altered by contact metamorphism. The prism shaped green crystals form as secondary deposits in granitic rocks, and are composed of uranium. The ore is very hard and has a measurement of 6.1 on the specific gravity scale. Arsenic is often obtained by heating the ore arsenopyrite, FeAsS. Arsenopyrite is a mixture of arsenic and iron sulphide. German geologists used to call it mispickel. Arsenic levels in the environment can vary by locality, and it is found in water, air, and soil. Link to MinDat.org Location Data.

In general, arsenopyrite is found in the Franklin Marble, and loellingite is found in the orebodies. With comparable constituent electronegativities and a white-line feature in the XANES indicating unoccupied Au 5 d -states, but absorption-edge positions comparable to Au 1+ species, the bonding is interpreted as being covalent rather than ionic. At Tsumeb, Namibia, arsenates generally dominate the secondary assemblage, whereas at Broken Hill, in New South Wales, Australia, both phosphates and arsenates occur. There is also used a "Lead Flux" mixture of Sodium bicarbonate, Potassium carbonate, Borax-glass, Flour, and silica from powdered sand.
