Summary edit

Description
Deutsch: Pyrit, de:Quarz
Größe: 6,2 cm
Fundort: Spruce Claim, Washington, USA
Beschreibung: Eine Probe von Pyrit und Quarz. Eisenpyrit, aufgrund seiner Ähnlichkeit mit Gold auch als Narrengold bekannt, kommt häufig in Quarzadern vor. Pyrit ist eine wichtige Quelle für Schwefeldioxid, aus dem hauptsächlich Schwefelsäure, eine wichtige Industriesäure, hergestellt wird. Tatsächlich wurde der Verbrauch von Schwefelsäure als einer der besten Indizes für die industrielle Entwicklung eines Landes angesehen. In den USA wird jedes Jahr mehr Schwefelsäure produziert als bei jeder anderen Chemikalie. Weitere Informationen zu Schwefel finden Sie auf der USGS Minerals-Webseite: https://minerals.usgs.gov/minerals/pubs/commodity/sulfur/

Locality: Sample originated from Spruce Claim, Washington
Description: A sample of pyrite and quartz. Iron pyrite, also known as Fool's Gold due to its resemblance to gold, often occurs in quartz veins. Pyrite is an important source of sulfur dioxide, which is primarily used to create sulfuric acid, an important industrial acid. In fact, consumption of sulfuric acid has been regarded as one of the best indexes of a nation's industrial development. More sulfuric acid is produced in the United States every year than any other chemical. For more information about sulfur, visit the USGS Minerals webpage: https://minerals.usgs.gov/minerals/pubs/commodity/sulfur/
