• Pyrite Mineral | Uses and Properties

    Pyrite as an Ore of Gold. The most important use of pyrite is as an ore of gold. Gold and pyrite form under similar conditions and occur together in the same rocks. In some deposits small amounts of gold occur as inclusions and substitutions within pyrite. Some pyrites can contain % gold by weight or more.

  • Pyrite: The mineral pyrite information and pictures

    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 goldbearing 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.

  • Jeff Wynn: Acid and Pyrite

     · Pyrite is commonly found in almost all sulfide deposits, and must be removed first to extract the gold, copper, molybdenum, silver, lead, tin, etc., being sought after. Our early ancestors – creators of the Bronze Age of ancient Greece – had already worked out much of this process millennia ago.

  • Are pyrite and gold found together? – AnswersToAll

     · To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods. Why is pyrite bad? Pyrite, which is a sulphide mineral composed of iron and sulphur, is a major contaminator of ground water and streams due to acid mine drainage from sulphide mine tailings.

  • Bioleaching of Gold Ore Example | GraduateWay

     · Gold ores rich in pyrite may need continual addition of lime to higher the pH to ideal processing levels. Pyrrhotite and arsenopyrrite are both highly acidconsuming and for ores with high concentrations of these minerals, additional acids may need to be added in order for optimal bacterial effectiveness.

     · What is Pyrite? Pyrite is a sulfide mineral containing iron (Fe) and sulfur (S) as structural elements. Its chemical formula is FeS 2. It is also known as iron pyrite and "fool's gold" due to its palebrass yellow color. In the ancient days, people misunderstood pyrite as gold since it possesses a yellowish metallic luster similar to gold.
