  • How to Separate Gold from Pyrite

     · The ores, which have been met with in various parts of the world, consisting mainly of limonite or hydrated oxide of iron, and in most cases believed to be the result of decomposition of pyritic ores by atmospheric agencies, are also extremely refractory, causing the mercury to sicken rapidly, and yielding only about the same percentage of gold as can be obtained from .

  • 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.

  • What is "Fool's Gold?"

    Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear goldlike, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will leave a golden

  • Dissolving Ore?

     · As for dissolving the gold that is not what I want, I want to dissolve the pyrite to get the free gold out. The idea of cooking it for a while sounds interesting but I don't think 400 degrees would be adequate, but its worth a try because it's not a large enough quantities to spend a great deal of money on, maybe a penny weight of gold.

     · 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.

But where things can get confusing is gold and pyrite sometimes turn up in the same deposits. Remember, Frobisher's ore did contain some genuine gold — albeit a teeny, tiny amount.

     · The first difference between pyrite and gold is the fact that pyrite isn't even a metal, it's a mineral. PYRITE — "a very common brassyellow mineral, iron disulfide, FeS2, with a metallic luster". GOLD — "a precious yellow metallic element, highly malleable and ductile, and not subject to oxidation or corrosion. Symbol: Au".

  • The Difference Between Gold and Pyrite

    Density: Pyrite ( g/cm 3) is much, much lighter than gold ( g/cm 3). Scrape: if you scrape gold on a piece of white porcelain, it will leave a yellow streak; pyrite's streak will be black. With these facts in mind, it should be easy for you to tell the difference between fool's gold and real gold.
