Professor of UT Dallas: pyrite is the most harmful mineral ...

‘In fact, pyrite binds arsenic in coal. When coal burns, pyrite is oxidized thus releasing arsenic. For instance, the occupational lung disease of miners is caused by pyrite. Pyrite is a main source of acid gases in the atmosphere. Therefore, I consider pyrite the most dangerous mineral for human health, - said the scientist.

Hydrogeologic and environmental impact of amjhore pyrite ...

Jan 01, 1991  Drainage from active and inactive pyrite mines has produced chemical and physical pollution of both ground- and surface water in Amjhore region. In the present case, chemical pollution is caused by exposing pyrite minerals to oxidation or leaching, resulting in undesirable concentrations of dissolved materials. Pyrite mining suddenly exposed large quantities of sulfides to direct contact with ...

Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore. Pyrite Uses

Pyrite - Wikipedia

The mineral pyrite , or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.
