The pyrite grade in the fresh tailing sample and in the flotation product was determined indirectly from the content sulfur, copper and iron. Calculations carried out considering the elemental chemical composition presented in Table 1 and the mineralogical species that contained sulfur, identified by the XRD analysis, allowed to determine that the fresh tailings sample contained 4.56% FeS 2 ...
Iron Pyrite or Pyrite is a mineral of Iron Sulfide and has a chemical formula FeS2, and a luster like a metal. Its color is brassy yellow that makes it look like gold, which brought in its name, "fools gold." It is quite easy to differentiate Pyrite from gold because of its higher hardness and the fact that it appears lighter than gold.
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 gold-bearing localities.Pyrite 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.

Pyrite glitters when exposed to light. When it is darker, however, Pyrite will not have any shine. Pyrite has sharp edges and its shape is a lot more angular.
Pyrite is very brittle, and shatters easily along the joins of the crystals. Unlike gold, it is not workable. Iron composes approximately 46% of the mineral, with the remainder made up by sulfur and trace impurities such as gold, nickel, arsenic, and copper.
