Pyrite is unstable and oxidizes easily, which is an issue in controlling acid mine drainage. Pyrite is a widespread natural source of arsenic, which can leach into ground-water aquifers when geologic strata containing pyrite are exposed to the air and water, during coal mining for example.
Arsenopyrite is generally an acid consuming sulfide mineral unlike iron pyrite which can lead to acid mine drainage. The crystal habit, hardness, density, and garlic odor when struck are diagnostic. Arsenopyrite in older literature may be referred to as mispickel, a name of German origin.
Pyrite contains sulfur in some locations, by pyrite mining to obtain sulfur, it resulted in sulphide mine tailings poisoning local water. Pyrite by itself is not harmful. Pyrite with veins of sulfur can cause a problem. On the other side Shungite.com states:
Back to Rocks and Minerals Articles Kathy Feick Pyrite group of minerals Pyrite Chalcopyrite Marcasite Arsenopyrite Chromate Copper Arsenate Pyrite FeS2 (Isoclinic) Pyrite's name comes from the Greek, pyrites lithos, "the stone which strikes fire." The crystals form in the Isometric System; cubes, octahedrons, pyritohedrons and combinations of these and other forms.
19th Century Pyrite Treatments. In the 1880s a large cache of Iguanodon fossils were discovered at a coal mine at Bernissart. L. De Pauw, director of the Royal Natural History Museum laboratory in Brussels recognized that the specimens were impregnated with iron pyrite and would be susceptible to "pyrite …

Precious minerals make the modern world go 'round—they're used in everything from circuit boards to tableware. They're also some of the most toxic materials known to science, and excavating them has proved so dangerous over the years, some have been phased out of industrial production altogether. Listed below are the 10 most deadly minerals on earth.
Indeed, the sulfuric acid produced by decomposing pyrite in combination with water can be dangerous ecologically. It may result in acid rock drainage as well as acid rain. This can be particularly dangerous when humans become involved. One well-known incident was the 2015 Gold King Mine wastewater spill.
Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
Framboidal pyrite in fine-grained dolomite matrix. Such pyrite aggregates, fairly common in some sedimentary rocks and low-temperature hydrothermal ore deposits, have formed due to bacterial activity. The individual crystallites, about 1 micron in size, are slightly rounded cubes. SEM photo (BSE mode). This photo was originally published ...

Arsenopyrite is arsenic iron sulfide, which is the same type of mineral as pyrite (fool's gold, iron sulfide), but with a heavy addition of arsenic. If one attempts to heat or in any way alter the mineral, a strong garlic odor of arsenic will be produced as lethally toxic, corrosive and carcinogenic vapors are released.

What is Pyrite? Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral.It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral.
Torbernite - Cu(UO2)2(PO4)2·8 - 12 H2O. #N#Torbernite from Musonoi Mine, Congo. Torbernite is a dangerous mineral composed of hydrated green copper, phosphate, and uranyl. The mineral is often found in granites that contain uranium and is dangerous due to its radioactive nature. The mineral releases radon naturally and can cause lung cancer if ...

Cabin Branch Pyrite Mine was huge - over 1000 feet long and 1000 feet wide, with an average thickness of 14 to 18 feet. In 1916, the American Agricultural Chemical Company began its 4 year ownership of the mine. The Cabin Branch Pyrite Mine was the only pyrite mine in Prince William County and the greatest boost to the local
