What is gold use for?

Precious metal known as gold has seen many uses over the centuries. While traditionally most common use is to create money, bars and jewelry, gold is also seen various uses less typical.

In some cultures, the Far East, gold leaf, flakes or dust, eating for health and as a show of wealth. It should be noted that he had swallowed a gold element in this way has not been proven to provide a significant impact on human health, but large doses can be toxic.

Gold is used for modern medicine in the form of salts or radioisotopes. Golden shapes can be used by the body when taken orally or by injection as a medical treatment to cope with a severe case of rheumatoid arthritis, tuberculosis, and other conditions. Isotopes of gold, gold-198, is also used to treat cancer.

Gold is often combined with other metals for use in modern dentistry. Gold is used in dental work, including fillings and crowns, which are generally white gold or gold alloy. When used in white gold, 15 karat gold purity or more commonly.

Due to the special nature of conductive, gold has become a popular choice in the industry and electronics. Almost all the high-tech equipment, from computers to cell phones, has several gold deposits. Moreover, the fact that the electromagnetic radiation reflected gold has made it a popular choice in the protection of expensive equipment or personnel may be exposed to infrared light or other electromagnetic radiation of high level.

World's Largest Gold Nuggets

#1 Welcome Stranger nugget weighing in at 2316 oz., found on February 5th, 1869 in Moliagul, Victoria, Australia. It was discovered by John Deason and Richard Oates just 2 inches below the surface near a root of a tree in Bulldog Gully.  It measured 2 ft x 1.02 ft in size.  Due to the size of the nugget it could not be weighed on any scales at the time and had to be broken down into 3 smaller pieces.  It was melted down shortly after finding and only recreations of the nugget made from drawings exist.  One replica of the "Welcome Stranger" nugget can be found at the City Museum in Treasury Place, in Melbourne, Victoria.  The other replica is owned by descendants of John Deason.

#2 Pepita Canaa nugget weighing in at 2145 oz., found Sept 13, 1983 by miners at the Serra Pelada Mine in the State of Para, Brazil.  It currently resides in the Banco Central Museum in Brazil.

10 Biggest Gold Mines in the World

The following list draws from each of these sources, as well as others, and thus is not a simple duplication of any one group's rankings.

1. Grasberg Gold Mine -- This mine, which is in the Indonesian province of Papua, produced 2,025,000 ounces of gold, according to the annual report of Rio Tinto Plc. The mine is majority owned by Freeport-McMoRan Copper & Gold Inc. Besides gold, it also produces silver and copper.

Grasberg - Indonesia

2. Muruntau Gold Mine -- This mine, which is about 250 miles west of the capital in Uzbekistan, is believed to have produced approximately 1,800,000 ounces of gold last year. The project, which is an open-pit operation, is run by state-owned Navoi Mining and Metallurgical Combinat.

What is Silver?

Silver chemical symbol and atomic number 47 (: άργυρος <Argyros> Latin, Argentum, or Indo - European root * arg for "gray" or "shining" in Greek) is a metallic chemical element with the AG. Soft, white, shiny transition metal, it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Its pure form, free (native silver) in metallic gold and other metals and minerals, such as argentite and chlorargyrite occurs naturally as an alloy. Most silver, copper, gold, lead, zinc, and is produced as a by-product of refining.

Silver is a very ductile malleable (slightly harder than gold), monovalent metal coins brilliant white metallic luster that can take a high level of gloss s highest electrical conductivity of all metals, even higher than copper, but the costs are becoming more and more widely used in place of copper for electrical purposes. Except radio engineering in the VHF and higher frequencies, where silver, including wires, improving the electrical conductivity of parts, widely used, particularly. During the Second World War, 13,540 tons electromagnets used for enriching uranium, mainly due to lack of copper used in time of war.
