Iron pyrite, the fool's gold of antiquity, turns out to be a useful indicator for those of us seeking the black gold of modern times, crude oil. Pyrite is a common accessory mineral in sedimentary rocks, particularly in limestone, sandstone and carbonaceous siltstones or shales.
Nov 21, 2008· Abstract Iron pyrites are waste products from mining operations and are also mined products. They have been used with varying success to supply Fe to plants, to supply S to plants, and to ameliorate sodic soils when oxidized to acid which forms gypsum in calcareous soil. Several forms of pyrite exist depending upon origin and crystallinity.
Fool's gold might seem like an unlikely pathway to low cost solar power but new research reveals some promise under the shiny skin of iron pyrite.
Pyrite roasting and sulphur burning plants are built for the production of sulphuric acid. Whereas the burning of elemental sulphur is the main source for sulphuric acid, the roasting process is an interesting alternative once pyrite concentrate is available.

pyrite is deffinently not good for the tank as it's flakey and breaks apart. so your fish might find it floating around the tank water and eat it then shortly die because they can't digest it. plus all the chemicals in pyrite would be devistating to the water's chemistry. gold is certainly better but not many people have nuggets of gold lying around.

May 10, 2011· The mineral pyrite, or iron pyrite, has a metallic luster and brass-yellow color that led to its nickname: fool's gold. In fact, pyrite is sometimes found in association with small quantities of gold.
The mineral pyrite or iron pyrite is commonly referred to as Fool's Gold because its metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, pyrite was sometimes mistaken for gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2.
Pyrite oxidation has been studied extensively, in the past, because of its importance in sulfide mineral separations by flotation, in the generation of acid in mine waters and in leaching of pyrite. The oxidation of pyrite also plays key role in supergene alteration of ore deposits, the formation of acid sulfate soils, etc. Pyrite oxidation is generally recognized as a complicated process ...
The choice of pyrite ore crushing method is according to ores characteristic, beneficiation site etc.Most pyrite ores contain sulfur and iron combination with coarser disseminated particle size above 1mm. sorting out the sulfur and iron element, and selling them to sulfuric acid plant, you will get considerable profits.

Pyrite cinders, which are the waste products of sulphuric acid manufacturing plants, contain hazardous heavy metals with potential environmental risks for disposal. In this study, the potential use of pyrite cinders (PyCs) as iron source in the production of Portland cement clinker was demonstrated at the industrial scale.
9.05.3.1.1 Mechanism of pyrite oxidation by Fe 3+ and O 2. Initially, pyrite oxidation involves the adsorption of O 2 and water to the partly protonated pyrite surface by bonding to Fe 2+ (Fornasiero et al., 1994).Various iron oxyhydroxide intermediate products can form on the pyrite surface, depending on pH.
The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).
Fool's gold scratches glass whereas real gold does not. Iron pyrite is attracted to magnets, but real gold is not magnetic. Real gold also leaves a gold streak when scratched against a small bit of unglazed ceramic, like the back of a piece of bathroom tile, but iron pyrite leaves a greenish-black colored streak.
Iron pyrite (FeS 2) is a promising material with plethora of applications ranging from sulfuric acid production to photo-voltaic devices.Interestingly, the proponents of the theory of hydrothermal origin of life on earth argues that FeS 2 may have evolved 4.0 billion years ago, and used as an energy source by the earliest evolving life forms on earth.
hydrometallurgical section of the plant. Pyrite concentrate Dead roasting is recommended when the pyrites have no trace of arsenic and when high metal recovery is critical. Iron sulfides are transformed into iron oxides, with the production of sulfuric acid being an important output of this process in terms of ensuring its economic viability.
Pyrite "Disease" Pyrite (or iron persulfide: FeS2), also known as "fool's gold," is a common mineral that is often found in sedimentary rock. In some fossil deposits pyrite gets incorporated into bone, invertebrate shell, and plant fossils during the process of fossilization.
Iron pyrites are waste products from mining operations and are also mined products. They have been used with varying success to supply Fe to plants, to supply S to plants…

Iron is also the metal at the active site of many important redox enzymes dealing with cellular respiration and oxidation and reduction in plants and animals. Chemically, the most common oxidation states of iron are iron(II) and iron(III).

Pyrite often replaces plant debris and shells to create pyrite fossils or flattened discs called pyrite dollars. In calcite and quartz veins, pyrite oxidizes to iron oxides or hydroxides such as limonite, an indicator that there is pyrite in the underlying rock. Such oxidized zones are called "gossan," which appears as rusty zones at the ...
