Hunting for pyrite (fool's gold) in the mountains

Hunting pyrite (fool's gold) in the mountains Today after traveling a long distance I finally reached this mountain place where I hunted some samples of Vic red jasper agate after successive searches I identified a suspected gold stone when I saw it very I was happy, but after removing it from the bottom, I realized that it is pyrite, or fool's gold
Pyrite or iron pyrite, which is called Marqishisha in ancient Persian texts, is a mineral with the chemical formula FeS2.

Pyrite is derived from the Greek word pyre, which means fire. Perhaps this name is due to the spark produced by collision with other stones. This mineral has been identified with marcasite in old mineralogy of Iran. In Farsi, the words "brinje" and "seng noor" are also used for pyrite. [source needed] Its chemical composition contains 46.6% iron and 4.53% sulfur, which is observed as FeS2. In terms of crystallography, it has a cubic crystallization system that is similar to table salt. In addition to cubic crystallization, pyrite can be seen as octahedral, pyritohedral, and sometimes dodecahedral. In addition to the mentioned elements, impurities of nickel, cobalt, gold, silver, molybdenum, chromium, vanadium, tungsten, thallium, copper, zinc, arsenic and titanium can be observed in the mentioned mineral. The luster and pale brassy yellow color of this metal makes it look similar to gold, and hence it is known as fool's gold. This color is also called brass, bronze, and Brazil, which primarily refers to the pyrite found in coal. will be .en: Pyrite's appearance is crystal, mass aggregate, granular, saturated dendritic, pseudomorph and powder. Pyrite is brittle in terms of hardness and has non-magnetic properties (diamagnetism). Its fracture is shell-shaped and mostly uneven, and its density is 1.5-4.95. Pyrite is insoluble in water, sulfuric acid and hydrochloric acid and it dissolves in nitric acid and turns blue under the flame. The melting point of this mineral is 1177 to 1188 degrees Celsius and it has moderate electrical conductivity. This mineral has a magmatic origin, adjacent alteration, hydrothermal and sedimentary and is associated with pyrrhotite, sphalerite, galena, chalcopyrite, calcite, quartz, barite, marcasite, arsenopyrite and hematite and is also formed inside coal. This mineral is used to prepare sulfuric acid and is used in dyeing, for polishing, rarely in the preparation of iron and in the preparation of sulfur dioxide in papermaking.

The existence of pyrite and its oxidation by bacteria is very important in the biological leaching of minerals, and sometimes it is added to mineral stones for the progress of the reaction. With the biodegradation of pyrite, sulfuric acid and ferric ions are produced, both of which can be effective in further decomposition of the rock.

In mines, pyrite is exposed to air and a slow spontaneous reaction with oxygen takes place. This initiator reaction leads to the creation of an acidic environment that is suitable for the growth of certain bacteria. These bacteria oxidize ferrous iron and create Fe2+, which is soluble in acidic pH and as a strong oxidizer can further oxidize pyrite and other minerals.
