Arsenopyrite is the chief ore of arsenic, and the primary ores for both copper and silver include arsenic-bearing minerals. Arsenic is also typically high in ores for gold, tin, tungsten, and lead. Most rock removed during mining operations is waste rock, left behind in tailings and waste piles. In some areas of the western United States, residential and other construction has occurred in close proximity to mining wastes, and some communities have elevated levels of arsenic throughout their.

Arsenopyrite is an iron arsenic sulfide with a chemical composition of FeAsS. It is the most abundant arsenic-bearing mineral and the primary ore of arsenic metal. It is associated with other sulfide minerals in organic-rich sedimentary rocks, metamorphic rocks, and igneous rocks in many parts of the world Arsenopyrite. Comments: Polished section (PPL) showing crystalline aggregate of arsenopyrite (asp) in massive sphalerite (sp), typical of the main sphalerite lens. Location: Giant Kidd Creek Volcanogenic Massive Sulfide deposit, Western Abitibi Subprovince, Timmins, Ontario, Canada. Scale: F.V. = 0.25 mm. © National Resouces of Canad Arsenopyrite is closely related to alloclasite, but is not an exact analogue, because of different As-S and S-As ordering. Arsenopyrite may contain up to about 9 wt.% Co; with higher Co contents, glaucodot will appear as a separate phase (Gammon, 1966). May be confused with the iron arsenide löllingite. Classification of Arsenopyrite Hid 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 Arsenopyrite is related to pyrite and marcasite. However, its silver color easily distinguishes it from its golden-yellow cousins. This mineral is opaque with a metallic luster, and it leaves a streak ranging from gray to black on a ceramic streak plate

  1. Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery. One of the more common classes of ores containing gold is when gold is associated with pyrite, pyrrhotite, and arsenopyrite. This is the area of gold recovery that has probably received the most research and plant optimization support especially in light of the long history of South African.
  2. Arsenopyrite has traditionally been considered to be chemically unstable in the surficial environment. However, field evidence demonstrates that arsenopyrite does not readily decompose under water.
