Gold is a chemical element in the periodic table that has the symbol Au (L. aurum) and atomic number 79. A soft, shiny, yellow, dense, malleable, ductile (trivalent and univalent) transition metal, gold does not react with most chemicals but is attacked by chlorine, fluorine and aqua regia. The metal occurs as nuggets or grains in rocks and in alluvial deposits and is one of the coinage metals. For millennia, gold has served as money and is also used in jewellery, dentistry, and in electronics. Gold forms t ...

In January 1959 US M3 money supply was $288.8 billion, and the Official Gold Holdings of the United States was then 17,335.1 Tonnes, or about 557 million ounces (there are 32,150.7 Troy Ounces in a Tonne). That means that in 1959, there were $518 in circulation for every ounce of gold reserves held by the USA. Although the theoretical price should then have been $518 per ounce, the actual price, as fi ...

Gold is a metallic element with a characteristic yellow color, but can also be black or ruby when finely divided, while colloidal solutions are intensely colored and often purple. These colors are the result of gold's plasmon frequency lying in the visible range, which causes red and yellow light to be reflected, and blue light to be absorbed. Only silver colloids exhibit the same interactions with light, albeit at a shorter fr ...

White gold refers to an alloy of gold and other white metals such as silver, palladium, or nickel. The natural color of white gold is light gray, so jewelry made of white gold is typically coated in highly reflective rhodium (sometimes coated in platinum and palladium), adding a more brilliant shine. Palladium and silver alloys are of higher quality than nickel and are sometimes not coated with rhodium. The purpose of plating is to add luster to grayer jewelry, as well as to prevent oxidation of some of the metals found in the alloys. ...

The Colorado Gold Rush was the boom in the prospecting and mining of gold in present-day Colorado in the United States that began in 1859 (when the land was still in the Kansas Territory) and lasted throughout the early 1860s. The gold rush, which followed approximately a decade after the California Gold Rush, was accompanied by a dramatic influx of emigrants into the region of the Rocky Mountains and exemplied by the phrase "Pikes Peak or Bust", a reference to the mountain in the Front Range that guided many early prospectors to the ...

After the Gold Rush is a 1970 album released by Neil Young. Neil Young's third solo album was a coda of sorts to the first, most prolific stage of his career: after leaving Buffalo Springfield in late 1968 Young had recorded two solo albums and the Crosby, Stills, Nash & Young Déjà Vu album in less than a year. Gold Rush was Young's most eclectic album yet, alternating the hard-rock that had made up the bulk of 1969's Ever ...

Colloidal gold is a suspension (or colloid) of sub-micrometre-sized particles in a fluid, usually water. The liquid is usually either an intense red colour (for particles less than 100 nm), or a dirty yellowish colour (for larger particles) [1] [2]. Known since ancient times, it was originally used as a method of staining glass; however, serious research into colloid ...

The California Gold Rush was a period in American history marked by mass hysteria concerning a gold discovery in Northern California. The period is also marked by mass migrations into California by people, almost exclusively men, seeking an easy fortune. Most, however, only found enough gold to barely pay for their daily expenses. The rush started at Sutter's Mill near Coloma, California on January 24, 1848 when James W. Marshall, an employee of Sacramento agriculturist John Sutter, found a gold nugget. Sutter wanted to suppress this ...

For over four thousand years gold has been regarded as a form of money and as a store of wealth. The use of gold superseded alternatives for a number of reasons including its rarity, luminosity, character (weight, softness), malleability, fungibility and resistance to tarnish. Since the collapse of the gold standard, gold has largely lost its role as a form of currency, but is still considered by many, especially by central banks, as a store of value and a safe haven in times of crisis. Gold and other precious metals are unique assets ...

Leaching might not work, if the gold is trapped within minerals which do not allow the leach solution access to the gold, and so the gold is not leached by the leach solution. If leaching doesn't work then this difficult to process (refractory) ore requires a refractory gold treatment step before cyanidation. These include: Concentrate or whole ore roasting Concentrate or whole ore bio-oxidation Concentrate or whole ore pressu ...

Soldering to gold-plated parts can be tricky. Gold dissolves in solder; an alloy of solder which contains more than 5% of gold can become brittle and the joint surface is dull-looking. If the gold layer does not completely dissolve in the solder, it may be pulled off the underlying surface later as the tin and gold atoms cross-migrate and undergo Kirkendall voiding, leading into a mechanical failure of the joint; a similar process on the gold-aluminum interface is known as purple plague. Thin layers of gold (under 20 mil) dissolve in the solder, exposing the ...

Investment in gold can be done directly through ownership, or indirectly through certificates, accounts, shares, futures etc. However, gold's benefit as a secure asset may only be truly realised when directly owned and stored in bullion or coins. Most investors would not recommend storing gold oneself (e.g. in one's home) but to use a bank or dealer. Other than storing gold in one's own safety deposit box at a bank, gold can also be placed in allocated (also known as non-fungible), or unallocated (fungible or pooled) storage with a bank or d ...

U.S. Gold - World Cup Carnival. U.S. Gold's most embarrassing moment came in 1986 with the release of World Cup Carnival on the C64, ZX Spectrum and Amstrad CPC. The company had acquired the rights to produce the official computer game of the Mexico 86 World Cup football competition well in advance of the planned release date. The game was to be developed in-house, but programming and marketing problems arose that were unable to be overcome in time for the game's release. At the eleventh hour, U.S. Gold ac ...

During the 1990s Russia liquidated much of the former USSR's gold reserves, while several other nations accumulated gold in preparation for the Economic and Monetary Union. The Swiss Franc left a full gold-convertible backing. However, gold reserves are held in significant quantity by many nations as a means of defending their currency, and hedging against the US Dollar, which forms the bulk of liquid currency reserves. Weakness in the US Dollar tends to be offset by strengthening of gold prices. Gold remains a principal financial asset of a ...
