Throughout this paper I will be discussing and researching the production of gold, platinum, and silver. Gold is a soft, bright yellow metallic element. Gold has been valued since the Stone Age. Platinum is a soft, ductile, silver white metallic element. Platinum was discovered in Columbia in 1735. Silver is a lustrous, white metallic element. Silver has been used for money since the time of Ancient Babylonian. I have researched all three and I will discuss its properties, uses, production, and its value.
Gold, which symbol is Au, is the first element that I will be discussing. Gold is a transition element in the periodic table and its atomic number is 79. Gold is very soft and easily transformed into many shapes and sizes. It is a good conductor of heat and electricity. Gold is inactive and is unaffected by air, heat, moisture and most solvents. It was first legalized as money as early as 1091 BC and in China as an alternative to silk. Gold is still the only universal accepted medium of exchange. Gold was found on the ground and used by prehistoric man as a tool. Art objects and jewelry made of gold were discovered by archaeologist, in Ur which is now Southern Iraq, this occurred around the period of 3000 BC. These art objects and jewelry were highly sophisticated and used in the Royal Tombs of Southern Iraq. In 1848, the true Gold Rush began. Millions of men rushed to California. The state was filled with men who had learned how to mine. These men spread throughout the West to hopefully strike it rich. These men used a circular dish to sift the bottoms of streams in search for gold. In the United States on September 24, 1869 we were faced with a short-lived financial crisis known as Black Friday. This was a period when the supply of gold was greatly in demand and two individuals, James Fisk and Jay Gould try to corner the gold market. This drove the price of gold up and threw the stock exchange into confusion. This panic had stopped when the U.S. treasury made additional reserves available for trading. As the demand for gold increased so did the ways in which gold mining developed. The mining for this element became much more elaborate and there were new inventions made to make this process easier.

Gold is produced in many different parts of the world. Approximately 80 % of the total worldwide production of gold now comes from South Africa, the United States, the former Soviet republics, Australia, Canada, China, and Brazil.
Gold is also used for unit of monetary exchange. Since ancient times gold has generally been the most readily acceptable form of currency. However, the use of gold coins was discontinued, for the most part, during the period between World Wars I and II. In the United States, which discontinued the use of gold coins in 1934, citizens may not own gold except in the form of jewelry.
Gold has the best working qualities out of all metals. One ounce of gold can be beaten out to cover an area of 300 square feet. It can be to a thickness of 5 millionths of an inch. Gold is usually combined with other metals to improve its wearing qualities because of its softness. Gold does not corrode or tarnish. Gold was often found mostly in low concentrations, over widespread areas of the earth. It often occurs in association with copper and lead as a trace constituent of the ores. In high concentrations, gold is usually encountered as the free metal; in this state it is generally associated with silver. Gold is also found in minerals, including calaverite. Gold is expressed in terms of karat systems. In the karat system the percentage of gold by weight is pure gold is 24 karat gold and 18 karat gold is 75 percent gold. The most common uses of gold are for jewelry. White gold was produced by the addition of Palladium to gold, but it is now manufactured from a gold nickel-alloy base. Gold alloys containing copper and red or pink in color and may be used for contrast in jewelry. The addition of silver to gold to form an 18 karat alloy gives a greenish color to the gold.

The mixture of 14 karat would be a combination of nickel and copper. Gold is currently used in the United States and the consumption is about $3.4 billion. The U.S. use of gold is divided up into the following percentages, 66 % in jewelry, 25 % in industry and 9% in dental. Most jewelry is manufactured in New York City and Rhode Island. This element has been of great value for the United States and other areas of the world. Platinum is back on the rise again. It is very popular and big on the market. It is more valuable than gold. It is relatively rare. Platinum is a soft, ductile, silver-white metallic element. Powder, spongy, and compact forms make up platinum. It has an atomic weight of 195.09. The symbol for platinum is Pt and its atomic number is 78. The Spanish scientist Antonio de Ulloa discovered platinum in gold-bearing deposits in Colombia in 1735. Platinum began to be used for jewelry in a significant amount in about 1905. A small amount of an alloying element such as iridium is added in jewelry because the alloy is harder than pure platinum. Also, platinum is used in dental fillings, and medical instruments. In addition platinum is used for electrical contacts, spark-plug electrodes, and a platinum-cobalt alloy is used in making powerful magnets.
South Africa, the Soviet Union, and Canada produce almost all of the world?s output of platinum, with the small remainder accounted for Columbia. World production of platinum increased strongly in the 1960?s and early 1970?s reaching roughly two million ounces (62 tons) per year. The production for platinum is in such great demand. Everybody seems to want platinum today. Silver, which symbol is Ag has an atomic number of 47. Silver is a lustrous, white, metallic element that conducts heat and electricity better than any other metal. It is the most flexible of all metals. The outstanding properties of silver include its great electrical and thermal conductivity. Silver is a rare metal that makes up less than a hundred-millionth of the earth?s crust. Silver was one of the metals known to ancient civilization, along with gold, copper, iron, tine, lead, and mercury. Pure silver is found in large masses of metals that could be used without complex separation and refinement. It was in great use in Egypt before 3500 BC. The leading silver-producing countries are the United States, Mexico, Canada, Peru, the USSR, and Australia.

The most common uses of silver are tableware, coins, and jewelry. Plated silver is also widely used in tableware and in jewelry. Tableware silver is made op of 92.5 percent silver and 7.5 percent copper. Silver plating is one of the most commonly used metals. It is used for electroplating either metallic or nonmetallic materials.
In the United States, silver shortly became involved in a contest between easy-money and tight-money system. In 1873 the prices of silver shifted again. Discoveries of silver in Nevada lowered its price of $1.293 an ounce. Silver-mine owners, farmers, and debtors, who wanted to increase the supply of money in rotation and bring about higher prices, began a campaign to restore bimetallism. One of the highest known companies for its establishment, is Tiffany and Company. Tiffany and Company was firmly incorporated in 1837. Tiffany and Company was first established at 259 Broadway in New York City. In 1845, the first mail order catalogue was published. This catalogue opened only eight years after opening. They then, the original firm company, moved to a bigger place at 271 Broadway in New York City. The firm consisted of Tiffany, Young, and Ellis. The firm acquires sizable collections of Jewels. Tiffany and Company consists of only world class diamonds. Charles Lewis Tiffany is known as ?The King of Diamonds.? This was the spring to manufacturing gold jewelry. In 1851 Mr. Tiffany hired John C. Moore. Moore was a prominent silversmith and this was the horizon to the beginning of design with manufacturing silver. By 1853 it was re-named Tiffany & Co by Charles Lewis Tiffany who had complete control. In 1861 when President Abraham Lincoln won presidency he bought his wife Mary Todd Lincoln a Tiffany seed-pearl jewelry.

Between professional servicing, most gold and platinum jewelry can be maintained with a nonabrasive cleaner. Examine your jewelry regularly to make sure settings are snug and clasps and joining are secure. Sterling silver tarnishes rapidly, especially when exposed to salt air and products containing sulfur, such as rubber bands and some papers. Tiffany and Company recommends a nonabrasive silver polish to keep your silver looking its best. Jewelry storage is important as well. At the time of purchase, all Tiffany and Company jewelry is wrapped in a protective box, case or tarnish-resistant pouch. Between wearing, it is recommend that you place it back in its original case or another suitable lined box or pouch.
