  • Pyrite Wikipedia

    Iron pyrite is unstable at Earth's surface: iron pyrite exposed to air and water decomposes into iron oxides and sulfate. This process is hastened by the action of Acidithiobacillus bacteria which oxidize the pyrite to produce ferrous iron and sulfate. These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is thehow is pyrite mined or extracted,A detailed look at The Concentrating Process Britannia Mine time, pyrite and sphalerite were not extracted.

  • Extracting Gold HowStuffWorks

    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.GMS Pyrite,Pick one up sometime and really examine it. I can tell you’re interested.
