How Gold Is Formed On Earth - Documentary Films. It is impossible to know the exact date that humans first began to mine gold, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria. The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old. A group of German and Georgian archaeologists claims the Sakdrisi site in southern Georgia, dating to the 3rd or 4th millennium BC, may be the world's oldest known gold mine.

Alien Gold. Why Extraterrestrials Mining Earth Gold? What Anunnaki Doing With Gold? Why We Love It?
 
18:42
Millennia fly by upon the Earth. Hundreds of generations changed. So many things changed. Yet, one thing remains unchangeable. Mankind love for gold. Indeed, why are we fascinated with this yellow metal? But the right question to ask would be why aliens made us love it. Do you know that bacteria exists that produces 24K or 99.9% pure gold. Yes, that bacteria literally poops the gold nugget by turning gold chloride—a toxic chemical liquid you abundant in nature—into 99.9% solid gold. In fact, Michigan state university has an entire lab filled with gold producing bacteria. I bet you didn't knew about it so stick around and you will find facts about gold that including why aliens use it and where is city of gold located. For that bacteria gold is toxic waste, because gold kills bacteria but their poop is our treasure. In fact, if you body is compressed each of us contain 0.2 milligrams of gold. Most of the gold is located in heart. So it's true that some of us have hearts of gold. And if that gold is extracted from all humans - it will be more gold than in the entire Unites Stares gold reserve. Gold, unlike bitcoin, is real physical thing. It is also relatively easy to mold producing the shapes that you want. You can use it for electronic conductors, you can wear it, you can eat it since it since it has healing effect on human body by gold nano particles eliminating harmful bacteria. Several restaurants around the world are serving you gold to eat. But each dish costs hundreds of dollars. I bet you are getting hungry just looking at these images. See how easy it's to manipulate human mind into something. It was even easier for aliens to manipulate early humans to love and adore gold. This is solid 24K carat gold disk. It first appeared two and half thousands years ago in Rome before Roman Republic or Empire even existed. It is so perfect that it would be hard to produce even using the modern technology. In fact, it was made by Anunnaki aliens hundreds of thousands years ago along with many other gold artifacts you are seeing now. Alien contacts started millions of years ago when first Anunnaki aliens came to mine gold and other metals from earth. Why did they came all the way here? Because unlike most of other small planets Earth suffered a catastrophic collision with planet Thea in the past that nearly destroyed Earth and created Moon but it also throw gold and other heavy metals on earth surface from it's core, making Earth so desirable for mining when on other planets aliens had to drill the core to get molten heavy metals, while on earth they were cool and ready right under their feet or tentacles. To assist in gold mining and service Anunnaki played with DNA of great apes to create what he know as humans today. So the point to Charles Darwin here - we are great apes descendants. Once they minded most of it - they left - leaving a few pyramids constructed by humans as a reminder of ancient aliens landmarks. And they also left one thing on Earth behind - our genetic love for gold. That's why to this day we are fascinated with gold and literally worshipping gold. Most of Earth deities are made from gold - from gold crosses on top of the churches to the gold Buddha. And you don't even suspect that those gold idols are actually representing aliens that visited earth and genetically modified us to love gold in order to find it and mine it for their alien needs. Only few selected humans were choosed to wear gold throughout our history and they also were worshipped like Gods. I put gold Santa Clause under our Christmas tree and to my dog was not impressed. But when my girlfriend saw it she was ecstatic. And the answer to this behavior difference - aliens. Aliens didn't need much gold for their space ships because as building material gold is impractical because its very heavy and very soft in its pure form. There spaceship made of gold would not fly far. It's only humans who can build their cars from gold. Even this small car made of gold weight several tons. Aliens needed gold to use on their skins and in their atmosphere, since it's the only antibacterial substance that does not have any side effect and can be used on humans, animals or aliens body. You can breath it, eat it, wear it and, unlike other metals, it will only make you healthier. Aliens used gold nano particles in their atmosphere because it was blocking harmful Ultraviolet rays of their star, deflecting star light to prevent global warming of their planet, making their air healthier to breath, and killed all harmful bacteria in the air and on the surface. Now you understand that gold has universal value but we humans using it the mostly wrong way by hoarding it in bars and coins instead of using it for our health needs and to prevent global warming by making gold nano particles deflecting part of Sunlight and harmful UV rays

It occurs in basically all mineral environments, and is the important constituent of many rocks. Quartz is also the most varied of all minerals, occurring in all different forms, habits, and colors. There are more variety names given to Quartz than any other mineral. Although the Feldspars as a group are more prevalent than Quartz, as an individual mineral Quartz is the most common mineral. Most mineral reference guides list Chalcedony as an individual mineral, but in reality it is a variety of Quartz. It is the microcrystalline form of Quartz, forming only occurs in microscopic, compacted crystals. This page deals only with the crystalline forms of Quartz. Chalcedony is listed on its own dedicated page in this guide. Other important varieties of Quartz, such as Amethyst, Citrine, and Agate, also have dedicated pages due to their popularity and individual varieties. Some forms of Quartz, especially the gemstone forms, have their color enhanced. Almost all forms of the yellow-brown variety Citrine are in fact heat treated. Much Amethyst is also heat treated to intensify color, and a green transparent form known as "Green Amethyst" or "Prasiolite" is formed by heat treating certain types of Amethyst. There is also a transparent sky blue form of Quartz crystals, as well as a wildly iridescent type that are synthetically colored by irradiation of gold. In some localities, Hematite forms a thin red or brown layer internally in the Quartz crystal, giving it a natural bright red to brown coloring, and sometimes even a mild natural iridescence.

Gold Mining Documentary - How Gold Is Mined, Refined And Formed - Prehistoric TV
 
42:24
Gold Mining Documentary - How Gold Is Mined, Refined And Formed - Prehistoric TV Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars,[6] and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core. Therefore, most of the gold that is in the Earth's crust and mantle is thought to have been delivered to Earth later, by asteroid impacts during the Late Heavy Bombardment, about 4 billion years ago.[7][8] Gold is resistant to most acids, though it does dissolve in aqua regia, a mixture of nitric acid and hydrochloric acid, which forms a soluble tetrachloroaurate anion. Gold is insoluble in nitric acid, which dissolves silver and base metals, a property that has long been used to refine gold and to confirm the presence of gold in metallic objects, giving rise to the term acid test. Gold also dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold dissolves in mercury, forming amalgam alloys, but this is not a chemical reaction. Historically, the value of gold was rooted in its relative rarity,[9] easy handling and minting, easy smelting and fabrication, resistance to corrosion and other chemical reactions (nobility) and its distinctive color.[10] As a precious metal, gold has been used for coinage, jewelry, and other arts throughout recorded history. In the past, a gold standard was often implemented as a monetary policy, but gold coins ceased to be minted as a circulating currency in the 1930s, and the world gold standard was abandoned for a fiat currency system after 1976.

Gold Nuggets On Bedrock & In Moss - The Ultimate Placer Deposit
 
09:21
Big chunky gold found on bedrock and I'm moss at our ultimate placer deposit. Gold found in every pan! Another gold mining adventure! Shown is 2 of 20 pans all will good sized gold nuggets and pickers! Good chunky placer gold is found in the creek and banks up to 3 meters out of the creek. The creek is in a canyon which is a 400 meter long hike and 200 meters in elevation hike. The area has minimal workings however there are several showings on the other side of the mountain which we have claims on. Could they be associated?? We are hoping to find the source maybe a huge gold quartz vein?? We believe the source of the gold is very close as most if the gold is in nugget form. Chunky gold can be seen in most pans along with black sand (magnetite and hematite). In the video we do ten pans only in this area. We will be exploring this area further and hope to eventually find a bedrock exposure or vein which is producing the gold. Hope everyone enjoys the video and stay tuned for more!

Gold Fingers - How to Recover Gold from Electronic Scrap

http://www.goldnscrap.com In this video tutorial i'm showing how to recover gold from electronic circuit board scrap. Specifically the gold plating that is found on the board connector edge - A.K.A the "fingers". This video is a complementary to the complete written tutorial on Gold-N-Scrap website (direct link below) The process applies to other kinds of gold plated itmes, given the substrate is unreactive (such as PCB, ceramic, glass etc'...). This process is less suitable for metallic items that are gold plated such as gold plated pins and gold filled items, though it will work with much effort and large consumption of acid. Post a comment and let us know how much gold do you think this recovery process yielded.

How To Invest In Gold: Gold Investing The Safe and Secure Way
 
02:36
How To Invest In Gold - http://InvestingInGoldAdvice.com - Click on the link here for my website where you can get comprehensive help and guidance on all matters relating to investing in gold including: - How to invest in gold safely and securely - How to avoid the mistake most first time gold investors make - How to get the maximum return from minimum risk when gold investing - Ways to invest in gold to protect your retirement plan - Where to buy gold competitively and risk free - How to get started investing in gold - Real time gold price chart - Daily gold market reports - Investing in gold videos by industry experts - and loads more!...in general, a 'one stop shop' for potential gold investors How To Invest In Gold Here I will give you some information about how to invest in gold by touching on the many different ways in which you can buy and keep the metal, directly or indirectly. Read on to know about seven different ways on how to invest in gold. 1. How to Invest in Gold in the form of Gold Coins Gold coins are of two types: bullion gold coins and collectors' coins. Bullion gold coins are more standardized in price and weight, whereas the value of collectors' coins is more subjective, depending on factors other than just their weight in gold. 2. How to Invest in Gold in the form of Gold Bullion Bullion refers to gold or silver in a form where only its weight is taken into account. Two of the most popular forms of gold bullion are gold bullion coins and gold bars. Both are available in standardized format and weights, though coins are more easily available. 3. How to Invest in Gold in the form of ETFs Exchange Traded Fund is a general term which refers to a mutual fund that can be bought and traded on a stock exchange. Gold ETFs are funds that buy and hold gold, so buying shares in gold ETFs makes you a mutual owner of gold. Gold ETFs are the most popular electronic or indirect way to invest in gold, as seen from the fact that the largest gold ETF has total assets worth more than $70 billion. The name of the fund is SPDR Gold Shares. 4. How to Invest in Gold in the form of ETCs Exchange Traded Commodities are much like ETFs, in that they own and track a number of different commodities in different ratios. Just like buying a gold ETFs, you can buy ETCs using your stock trader's account. 5. How to Invest in Gold in the form of ETNs An Exchange Traded Note (ETN) is another form of instrument whose value depends on the futures market for a particular commodity. You can buy an ETN for gold using your stock trader's account. Two popular ETNs are DB Gold Double Short and DB Gold Double Long. 6. How to Invest in Gold in the form of Jewelry When you are buying jewelry as a form of gold investment, it is important to go for a piece that is not too stylish or ostentatious; otherwise, its value will derive more from the craftsmanship of the piece rather than gold. 7. How to Invest in Gold in the form of Gold Mining Stocks Buying shares in gold mining companies is another way to invest in gold indirectly. The prices of shares of these companies are dependent not only on gold prices but also on management performance and local mining conditions. The above mentioned methods on how to invest in gold should allow you to diversify your portfolio by investing in gold, and reduce the risk of exposure to only stocks and other assets.

Mining Herkimer Diamonds
 
03:57
This short clip is a glimpse of us mining Herkimer Diamonds at Crystal Grove Diamond Mine just outside of St Johnsville, NY. For those of you who may be unfamiliar, Herkimer "Diamonds" are a form of clear quartz that sometimes develop double terminated crystals. Good specimens form loose in a vug, or pocket, without attaching to the dolomite that surrounds them, resulting in perfect 6-sided "football shaped" forms that are water clear. Check out our Etsy Shop if you're interested in purchasing some of our extra crystals. https://www.etsy.com/shop/DigItGemsandMinerals #OakKnobFarm #HerkimerDiamond #Mining

Originally a public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Lead Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Lead has been commonly used for thousands of years because it is widespread, easy to extract and easy to work with. It is highly malleable as well as easy to smelt. Metallic lead beads dating back to 6400 BCE have been found in Çatalhöyük in modern-day Turkey. In the early Bronze Age, lead was used with antimony and arsenic. The largest preindustrial producer of lead was the Roman economy, with an estimated annual output of 80,000 tonnes, which was typically won as a by-product of extensive silver smelting. Roman mining activities occurred in Central Europe, Roman Britain, the Balkans, Greece, Asia Minor and Hispania which alone accounted for 40% of world production. Roman lead pipes often bore the insignia of Roman emperors (see Roman lead pipe inscriptions). Lead plumbing in the Latin West may have been continued beyond the age of Theoderic the Great into the medieval period. Many Roman "pigs" (ingots) of lead figure in Derbyshire lead mining history and in the history of the industry in other English centers. The Romans also used lead in molten form to secure iron pins that held together large limestone blocks in certain monumental buildings. In alchemy, lead was thought to be the oldest metal and was associated with the planet Saturn. Alchemists accordingly used Saturn's symbol (the scythe, ♄) to refer to lead. Up to the 17th century, tin was often not distinguished from lead: lead was called plumbum nigrum (literally, "black lead"), while tin was called plumbum candidum (literally, "bright lead")... Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Ores are crushed and concentrated by froth flotation typically to 70% or more. Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silicates of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a coke-fired blast furnace to the metal. Additional layers separate in the process and float to the top of the metallic lead. These are slag (silicates containing 1.5% lead), matte (sulfides containing 15% lead), and speiss (arsenides of iron and copper). These wastes contain concentrations of copper, zinc, cadmium, and bismuth that can be recovered economically, as can their content of unreduced lead. Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. The melt is treated in a reverberatory furnace with air, steam, and sulfur, which oxidizes the contaminants except silver, gold, and bismuth. The oxidized contaminants are removed by drossing, where they float to the top and are skimmed off. Since lead ores contain significant concentrations of silver, the smelted metal also is commonly contaminated with silver. Metallic silver as well as gold is removed and recovered economically by means of the Parkes process. Desilvered lead is freed of bismuth according to the Betterton-Kroll process by treating it with metallic calcium and magnesium, which forms a bismuth dross that can be skimmed off. Very pure lead can be obtained by processing smelted lead electrolytically by means of the Betts process. The process uses anodes of impure lead and cathodes of pure lead in an electrolyte of silica fluoride...

How is Coal Formed? - Geography for Kids | Educational Videos by Mocomi
 
01:52
http://mocomi.com/ presents : How is Coal Formed? Millions of years ago, a large number of plants and ferns grew on Earth. These plants and ferns died in swamps, around riverbanks and got covered with soil and mud and slowly sank into the ground. As the years passed, the Earth’s heat and the weight of the ground changed these dead plants into coal. To extract coal, it needs to be dug out. Coal is usually found in layers, or seams underground. Learn more about where do we get coal and how does it form with the help of this animated learning module for kids. To learn more about where we get coal from, read: http://mocomi.com/where-do-we-get-coal-from/ For more geography related videos and interactive articles, visit: http://mocomi.com/learn/geography/ Follow Mocomi Kids - Top educational website for kids, on Facebook https://www.facebook.com/mocomikids/ on Twitter https://twitter.com/MocomiKids on Pinterest https://www.pinterest.com/mocomikids/ on Google+ https://plus.google.com/+mocomikids/ on LinkedIn https://www.linkedin.com/company/mocomi-kids

Alaska gold mining

Alaska gold mining, Invest in an Idaho gold property. A great asset to add to your portfolio and Great Elk Hunting!! FINANCING ZERO DOWN $200/MONTH!! Email me for more info and pictures. Thanks, Travis Hollon. (208)-628-3691 Here is some information on what a mining claim is and what you can do with one. This is a 20 acre unpatented mining claim, which means it's mineral rights only. Mineral rights are considered real property. The deed is held by the Federal Gov. These claims are located in National Forest. You own the minerals and they come with a federal serial number. You have more rights to the surface than the general public. Mining claim owners who own mineral rights have many privileges that most people are not aware of. With an approved plan of operations you can build temporary structures such as living quarters or storage sheds, out houses, etc. You can live on your claim for extended periods of time, even year around, if you are planning on testing or working your claim. You can build new roads and trails, cut timber, build a fence around your gold mine, etc. An unpatented mining claim is perpetual. It can be bought, sold, traded, or willed and can be maintained forever in one of two ways. One, is pay an assessment fee of $155 every year. Two, is filing a waver and an affidavit that states that you did $155 worth of assessment work on your claim for the year. It costs $10 to file these forms. In completion of one of these options, this claim will remain yours, with a federal serial number. A mining claim is a great asset to ad to your portfolio. Mining claims in the desired Florence Basin will be worth more in the future as gold prices rise, making your investment worth more!! This claim is 20 acres of prime mineral rights in a proven gold discovery. Call or email for more info. Thanks for your time! Travis Hollon (208)-628 3691

What is GOLD LAUNDERING? What does GOLD LAUNDERING mean? GOLD LAUNDERING meaning - GOLD LAUNDERING definition - GOLD LAUNDERING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Gold laundering is the process whereby illegally obtained gold is melted and recast into another form. The recasting is performed to obscure or conceal the true origin of the gold. The recast gold is then sold, thus laundering it into cash. It may also refer to a money laundering transaction in which the exchanged good is gold. There are several stages in the gold laundering process. The first is the acquisition of the gold, which may be from any combination of sources, at least one of which is illegal. This is then treated as scrap metal, melted, then cast into a mold. This results in a transportable ingot, gold bar or other bulk form bullion. In some cases, there is no gold involved in the laundering scheme. Colombia reported 70 tons of gold exports for 2012 despite production of only 15 tons. This is a result of fictitious gold exports filed with the Colombian customs agency by drug cartels in order to import "cash from international drug deals". Acquisition of the gold occurs in many forms. Small-scale gold mining operations, particularly those with no permits or licences, extract gold from areas unsuitable for large mining operations. Gold obtained in this fashion that is exported may not be traced or authenticated. This includes artisanal mines operated by few individuals, who then sell the gold to brokers. Another form of acquisition is theft. In the 1940s, Nazi Germany forcibly obtained the possessions of Jews, sometimes in collaboration with other parties. Most victims who died in death camps and Nazi concentration camps were robbed of all valuable property by the state, which was then sold or, in the case of bullion, sent to the Reichsbank. For example, in 1945 the Hungarian Gold Train was established to transport the property of Hungarian Jews to Berlin. Once the Jews had been deported to German concentration camps, the valuables were sorted into categories such that their owners could no longer be identified. In the late 1930s and throughout World War II, Germany would increase its unofficial gold reserves by expropriating gold from foreign governments, including $223m from Belgium and $193m from the Netherlands. Some of the Nazi gold was exchanged for cash, and some deposited in financial institutions, including $316 million of the looted gold at the Swiss National Bank. Of the nearly 100 tons of gold laundered through Swiss banks, only 4 tons was returned. The Banco de Portugal, the central bank of Portugal, would regularly purchase Nazi gold held at the Swiss National Bank, according to a 1944 document from the American Overseas Special Services. The scrap gold is then sold by brokers to smelters or refiners, who heat the gold to at least 1,064 °C (1,947 °F), its melting point. This may include gold from numerous sources, including recycled and newly mined gold. Once melted, it may be purified by parting, which separates out silver impurities, and the Miller process or Wohlwill process, depending on the desired level of purity and scale of operation. Once refined, it is cast into a transportable form for further processing. Gold fingerprinting, that is identifying a particular source of gold based on its impurities or trace elements, may be possible if the impurities have not been removed via refining. To prevent laundering of gold and other metals (such as tantalum, tin, and tungsten), some nations have established systems and regulations. For example, Rwanda introduced regulations for mineral trade that requires all ore extraction be tagged, in part a response to the Dodd–Frank Wall Street Reform and Consumer Protection Act in the United States that requires companies to disclose the use of conflict minerals by publishing a supply chain audit. However, with only 100 government monitors overseeing 450 mining sites during typical business hours, smuggling still occurs, exacerbated by corrupt monitors illegally selling tags or failing to record transactions in logbooks. In 2013, Ghanaian president John Dramani Mahama announced that the government of Ghana would establish a task force to regulate the small-scale mining sector. This was to ensure that gold produced in small-scale mines could be authenticated, and also to eliminate the use of heavy machinery that had become prevalent on such sites, which have had caused environmental damage.
