Pyrite | Minerals Education Coalition

Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

University of Minnesota's Mineral Pages: Pyrite

As water moves through a pyrite-bearing rock, the pyrite's iron component may be oxidized, releasing its sulfur to form sulfuric acid. In natural settings this is seldom a concern, but pyrite-rich waste from mining operations can significantly increase the acidity of surface waters.

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 the ...

How to Separate Gold from Pyrite

So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier. Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here.

Oxidative Dissolution of Pyrite: A Combined Experimental ...

This work focuses on the geochemistry and iron isotope systematics of pyrite from hydrothermal and coal-forming environments. Dissolution of pyrite, even under abiotic conditions, is difficult to study experimentally and previous studies have demonstrated that the rate of pyrite oxidation is dependent upon environmental conditions. Knowledge of dissolution mechanisms enables more accurate ...
