Pyrite - Angola to Luxembourg
Posted by Rock Currier
Rock Currier June 24, 2010 10:27AMClick this link to view Pyrite from Mexico to Turkey and here for Pyrite from the United Kingdom to Zimbabwe. and here for Best Minerals P and here for Best Minerals A to Z and here for Fast Navigation of all Best Minerals articles.
Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?
Pyrite is the most abundant sulfide mineral, sometimes it occurs in masses of several thousand tons. It sometimes carries substantial values of gold and copper for which it is mined. Sometimes it is mined exclusively to produce sulfuric acid to which it is converted by “burning”. Mindat currently (2010) has listed more than 26,500 localities for Pyrite and more than 2,100 images of pyrite specimens. Almost certainly fewer than half the localities for pyrite are in our database. Below we will show pictures of several hundred of the best ones from just over 40 countries. The Hand Book of Mineralogy say crystals are up to about 25 cm and that’s about as big as any I have seen. This mineral has been know since ancient times and is also known as fools gold because at a glance it is sometimes mistaken for gold from which it can easily be distinguished by using a few simple tests, like hardness. You can't scratch it with a knife blade and gold is three times heaver by volume than pyrite. Crush some of it up on a can lid and heat it and it will give off SO2 and at least some of the resulting fragments will become magnetic. It has the property of giving off sparks if struck against something hard like quartz, iron or steel. Pliny in 77 AD said "there was much fire in it" and the Romans thought that perhaps it was "alive"? The name Pyrite was derived from the Greek word for fire. The crystals form in a variety of isometric crystal forms, but the most common are cubes and the ever popular hemi-tetrahexahedrons (pentagonal dodecahedrons but more commonly called pyritohedrons. The less common octahedral forms are perhaps the most cherished by collectors and the classical iron cross twins, though they don’t get very large and a bit too esoteric for most collectors. Some pyrite specimens have sold at auction for tens of thousands of dollars, which to old seasoned collectors seems ridiculous, but those are the facts.
Probably the best current locality for Pyrite would have to Huanzala Mine, Huallanca District, Dos de Mayo Province, Huanuco Department, Peru. It has produced probably the finest and largest crystals and crystal specimens as well as literally tons of specimens of pyrite crystals. At one time so many specimens were produced that crystal specimens were used as bases for pewter figurines, typically depicting miners and mining activities. One other springs immediately to mind and that is the locality of Navajún, La Rioja, Spain. This locality has produced tens of thousands of perfect cubic shaped crystals that often present in a fine grained light colored matrix and make striking specimens. These locality has been active for at least the last forty years and shows no sign of slowing its production. This locality is mined exclusively for its pyrite specimens where as Huanzala and most other prolific specimen producers are mined primarily for other minerals and frequently the pyrite ends up out on the dump. Historically the Island of Elba of the coast of Italy was the champion for producing specimens of pyrite, often associated with bladed hematite, but the 20th century came and went and the mines on are now mostly closed and good specimens from this locality are now not easy to find and are considered classics. The Spruce Claim in King County,Washington has also for many years been a favorite pyrite locality for serious collectors because of the sometimes stunning shiny cubic pyrite crystals growing with long white prismatic quartz crystals. These specimens are always very expensive if you can find a good one. Each season that the locality is worked produces only a few choice specimens, never enough to satisfy the demand. Undoubtedly in the years to come, many new localities will be found and mined that will produce fine pyrite specimen that will be added to those localities and specimens described below.
There is a type of pyrite that I like to think of as nodular or concretionary pyrite. It forms most commonly in fine grained sediments like shale or marlstone and is found frequently as balls or oblate spheroids (flattened balls) and disks, sometimes very flat like the pyrite "dollars" or "suns" from Illinois, USA. Sometimes they are elongated and worm like. The pyrite crystals that form these types of pyrite are usually not very distinct and sometimes one needs to look carefully with a microscope at the surface of these kinds of pyrites to see the isometric nature of their crystals. These kinds of pyrites are often not stable over long periods of time and are prone to decomposition caused by "pyrite disease" which has been attributed to a variety of causes. Some say that Marcasite is mixed in with the pyrite from some of these concretionary forms and that water and or bacteria act on the iron sulfide causing the generation of "acid" which then causes further decomposition of the specimen. I don't know of any authoritative paper on the subject and hope that someone reading this can point us to a really reliable source of information about this phenomenon. Sometimes the decomposition is so severe, that the specimen ends up in a pile of gray/white fragments and the "acid" generated by the composition eats up the box that the specimen has been kept in and on two of occasions I have seen where it has actually eaten its way through the bottom of metal drawers. As with many other minerals I believe that pyrite is best preserved by keeping it in a cool, relatively dry place with constant humidity and temperature.
Pyrite will oxidize and will loose its luster if you don't take care of it. If you place a specimen out in your garden it will loose its luster and become dull in a few years. On entering Quiruvilca, Peru, there is a concrete welcome monument whose concrete has been studded with surprisingly well formed pyrite crystals from the mine. When I saw it they were all dull and I realized after studying them closely that almost certainly when the monument was built, that the pyrites were almost certainly brilliant and shiny and this was confirmed by some of the miners in the camp. I have encountered pyrite specimens where finger prints have been plainly etched into what were at one time brilliant mirror like natural crystal faces. Is there any way to bring dull pyrites back to life and make them brilliant and shiny? Well, not that I know about, but if the specimen is not too far gone I have had success in cleaning them and making them a more shiny by the use of a commercial cleaning liquid called LimeAway which has phosphoric acid as its most active ingredient. Put the specimen you want to clean in water to fill up all its cracks with water and then dip a tooth brush in the Lime-Away (a 10% solution of phosphoric acid and water would probably work about as well) and brush it on the pyrite crystals and let it sit for a few minutes and then wash it off with water. Soak the specimen in fresh water and repeat the rinse cycle if necessary to make sure that all of the acid is gone from the specimen. The resulting shine, if any will be about as much as you can to to make your pyrite specimen look better. As crazy as it may sound, I would advise you to not handle your pyrite specimens with your bare hands, and if you do, to use a soft cloth or tissue to polish off any finger prints you or your friends may have left on the specimen. If you do take good care of your pyrite specimens, there is no reason that they won't last your lifetime and that of your children.
PyriteAngolaUíge Province, Mavoio Mine
Usually I would not include a pyrite of this low quality, but it is the only image of a Pyrite from Angola in our database and it can act as a place holder till we can get a better one and find someone who can tell us about the locality.

Probably should have not included this one here, but the mine almost certainly produces better specimens than this one.
PyriteAustraliaNew South Wales, Yancowinna Co., Broken Hill
Broken Hill is famous old mine that began its life as a silver mine and then after the rich silver content of its minerals diminished it continued as a great producer of copper, lead and zinc. Even though it does not produce very good pyrite specimens, many collectors are interested in minerals from this classic locality that I thought it wise to include an example of pyrite from this locality.

Bolivia has not produced anywhere near as much pyrite as neighboring Peru, although pyrite is widespread in many of Bolivia's tin mines and tin-silver mines, less common in tungsten, bismuth or antimony mines. Most bolivian pyrites are cubes, octahedra, cubo-octahedra combinations, sometimes with diploid faces. Pyritohedra, so common elsewhere, are quite rare in Bolivia, whereas octahedra are relatively more common than in other countries.
PyriteBoliviaCochabamba Department, Ayopaya Province, Kami Mine
These distorted pyrite crystals with depressed faces or, in extreme cases, saddle-shaped edges, were first offered to visiting dealers at the Kami mine by campesino children in the early 1990s. They apparently don't come from the mine itself, but from the country rock, slightly metamorphosed shales or hornfels, at some distance from the mine.
PyriteBoliviaLa Paz Department, Inquisivi Province, Chicote Grande, Lapiani Mine
The pyrites from the Lapiani tin mine occur as groups, and individual floater octahedra up to 7cm in size, in the vein gouge (clay filling), mostly extracted from the 1940s to 1970s. Although it is located in La Paz department, it is just across a narrow canyon from the Kami mine in Cochabamba department and is part of the same tungsten-tin mining district.
This specimen is probably from the Canutillos mine, the Colavi mine, or one of the other mines in the Machacamarca-Colavi district, for which the curved faces and association with siderite is typical.
PyriteBoliviaPotosi Department, Antonio Quijarro Province, Tolopampa, Cerro Ubina
PyriteBoliviaPotosí Department, Antonio Quijarro Province, Tolopampa, Cerro Ubina, Mr. Pickering's mistress' mine
For those that know little or nothing about Bolivian specimen localities, the name of this locality "Mr. Pickering's mistress's mine sounds quite improbable. However, the comments of Tony Potucek:
I had a specimen of pyrite from Mr. Pickering's Mistress Mine that I acquired from Mark Bandy with his label. Les Presmyk also had a couple of them. While I have long since traded or sold it away, Mr. Bandy thought enough of the locality to actually attribute specimens from there. Being younger and still quite randy when I owned the piece, the mine name conjured up some great day dreams for me as I went about banging on outcrops and wondering what Mr. Pickering's mistress looked like, and .... Well, you get the picture.
Mark Bandy was a mining engineer who worked for Simon Patino (the King of Tin) at Llallagua and an avid mineral collector. The fact that he thought the locality valid, carries a lot of weight.

PyriteBoliviaPotosí Department, Nor Chichas Province, Atocha-Quechisla District, Cerro Tazna, Tazna Mine (Tasna Mine; Tazna-Rosario Mine)
Tasna is better know for its specimens of Ferberite and Siderite, but it does produce the occasional good specimen of pyrite. Pyrite crystals from Tasna tend to be octahedral.
PyriteBoliviaPotosí Department, Rafael Bustillo Province (Bustillos Province), Llallagua
Llallagua is better know to collectors for its specimens of Paravauxite and Wavellite but it does produce decent Pyrite specimens occasionally. The first two are from the collection of Mark Bandy so we tend to believe their locality is accurate.
PyriteBoliviaPotosí Department, Sud Chichas Province, Atocha-Quechisla District, Chocaya mine
PyriteBrazilSoutheast Region, Minas Gerais, Francisco Dumont municipality
Sometimes large well formed pyrites are found in clear quartz. For many years this locality was unique in this regard and is still considered the best locality for such items. It is an old locality that produced almost all of its specimens before World War II. Specimens were never common and are rarely offered for sale. The two pictured here are quite good, but I know of one better. There are many localities where small mm size pyrites are found in quartz.

PyriteCanadaNunavut Territory, Baffin Island, Nanisivik, Nanisivik Mine
This base metal mine whose main ore is sphalerite has produced many remarkable specimens of pyrite. Certainly some thousands of specimens due mostly to the efforts of Rod Tyson who for several years, with an arrangement with Strathconia Mineral Services Ltd, the operating entity for the mine, worked in the mine and collected many fine specimens. The mine operates in an area north of the Arctic Circle where the permafrost is about 500 meters deep and the average temperature of the underground mine is -15 degrees C. During the summer, humid air from the surface pumped through the mine causes everything to be coated with up to a half meter of ice, sometimes in fine crystals. Collecting during this time is almost impossible and is left to the winter months when the working are mostly ice free. I remember Rod telling me about how all the pockets containing pyrite were full of ice and that after he had hacked out his specimens, he had to transport them to the surface where he could let the ice melt off of them and see the quality of the specimens that he had collected. The mine is on an old Mississippi Valley Type deposit which hosted many fine Marcasite crystals as singles, twins, and fiveling twins with little if any pyrite. Then in a later episode the ores were reworked dissolving the Marcasite and redepositing it as Pyrite. Inintially the pyrite came in as an oriented overgrowth on the remaining Marcasite. This epitaxi shows the relation between the crystal structure of Marcasite and Pyrite. The disulfide lattice is continuous between the two minerals. As the reworking continued all the Marcasite was pseudomorphed by Pyrite and the Pyrite continued to deposit both on the Pyrite in epitaxi and separately as more normal looking Pyrite. So many of the pyrite crystals are actually pseudomorphs after Marcasite and in some of the articles I have read call them pyritized Marcasite. The mine can only be reached by sea during the summer months or by air, and there are no facilities available at the mine except those provided by the mining company, so it is not a place where you can go for a field trip without making arrangements with Strathconia Mineral Services Ltd. Sadly that was before 2002 when the mine was shut and decommissioned. A good article to read about the locality is in the Mineralogical Record 1990, V.21 #6 p515-534

PyriteChinaGuangxi Zhuang Autonomous Region, Wuzhou Prefecture
I call these types of pyrites concretionary pyrites and they are commonly found in shale and find grained sediments. Frequently these types of pyrite are not as stable as their more well crystalized cousins from base metal mines. These are no exception. These pyrite "suns" are found up to about 6 inches in diameter, but the larger ones are notoriously unstable and in all the large ones I have seen, have cracks and fall apart in a month or two. The smaller ones appear to be much more stable and I have some that have thus far shown no decomposition in the five or six years I have had them. About one in every thousand or two thousand is actually a pyrite "donut" with pyrite crystal faces covering all surfaces of the "donut". Ill take some pictures of these and post them in the Mindat gallery and here when I get the time.

PyriteChinaHubei Province, Huangshi Prefecture, Edong Mining District, Daye Co., Fengjiashan Mine (Daye Copper mine)
Daye is a city in Hubei province and the seat of a 2000 year old bronze culture and is still a mining center with a big open pit copper mine on the edge of town. The Fengjiashan (Feng family mountain) mine is an underground mine, thought not a really big one and started life as a copper mine, but has recently taken to mining Sillimanite for refractory purposes. It is well known to collectors for many kinds of specimens including good pyrite specimens. Though the specimens from this mine may not rival the best of those from mines in Peru the best pyrites from here are avidly sought by collectors.
PyriteChinaHunan Province, Chenzhou Prefecture
The pyrite and calcite specimens from this locality are fine examples of epitaxially oriented overgrowths of one mineral on another. For what ever reason, probably related to thermodynamic considerations, the pyrite found it congenial to grow on come faces of these calcite crystals but not others. This kind of mineral association, collectors have always found fascinating.

Mining in Japan is now almost non existent so the production of mineral specimens from Japan are not offered for sale in the USA and when they are, they are almost always earmarked by the dealer who has them for sale directly in Japan or are bought directly by Japanese collectors. After the Second World war there was still some mining going on in Japan, and specimens sometimes made their way to the west because rich American collectors would pay more money for them than the few Japanese collectors. Today the tide has turned and the Japanese are repatriating their national treasures as fast as they can and they will usually pay more for them than will American or European collectors. As you can see from some of the above images of Japanese pyrite specimens, Japan has produced some very good specimen indeed.

Potosí Department, Antonio Quijarro Province, Tolopampa, Cerro Ubina, Mr. Pickering's mistress' mine
Can this be right? Would it not at least be in Spanish? Have you ever heard of mine name in Bolivia like that?
Crystals not pistols.
Alfredo Petrov July 16, 2010 12:23PMYes, I'd heard of "Mr Pickering's mistress' mine" before, but I'd assumed it was not the actual mine name but rather "the (unnamed) mine owned by Mr Pickering's mistress", so no need to translate it. Don't know who Mr Pickering was.... probably one of those randy British mine engineers who came to Bolivia hunting for tin between the 1880s and 1940s and had mistresses in every mining camp between La Paz and Atocha, and an extra one in Chile for good luck :)
Rock Currier July 16, 2010 06:50PMAlfredo,
would you have time to go through the Bolivian entries we have in this article and make some comments about the mines in general that they come from and something about the relative quality and abundance of the specimens that come from these mines?
Crystals not pistols.
Tony L. Potucek July 16, 2010 08:37PMHi,
I had a specimen of pyrite from Mr. Pickering's Mistress Mine that I acquired from Mark Bandy with his label. Les Presmyk also had a couple of them. While I have long since traded or sold it away, Mr. Bandy thought enough of the locality to actually attribute specimens from there. Being younger and still quite randy when I owned the piece, the mine name conjured up some great day dreams for me as I went about banging on outcrops and wondering what Mr. Pickering's mistress looked like, and how much it must have cost the old boy to sample her wares.
Rock Currier July 16, 2010 10:10PMTony,
That is good enough for me. If Mark Bandy gave it as a locality it is undoubtedly a valid one. I am going to use much of what you said in the article under Pyrite from that locality. If you have time, go through the pyrite localities and tell us what you know about them and the specimens that come from the localities. I have made you a level one member here on Mindat and you can now upload images to our database and add localities, but as far as localities are concerned you might want to run any proposed changes by us here on the message board till you get the hang of it. If you have more than just a few things to add to the Best Minerals pyrite articles or other Best Min minerals articles, Ill make you a helper and that will enable you to enter your comments directly into the articles.
