Silver is a pliable , malleable , and slightly harder than gold, with a shiny white metallic luster that can take a high level of finish . It has the greatest electric conduction in comparison to all other metals , even greater than copper, but its price has precluded it from being commonly utilised as the replacement of copper for conductive systems.

Silver is present in its original form, fused with gold or united with sulfur, arsenic, antimony or chlorine in alloys. Most produced silver is a byproduct of the filtering process of the compounded metals. Nevertheless, there are a number mines specially commited to the filtering of this component. Silver is a pretty rare component on the Earth's surface. Its abundance is assessed to be about 0.1 parts per million on Earth. As well as, it's been found in seawater and its excess there is believed to be more or less 0.01 parts per million.

Silver has exceptional place in the chronicle of elements as it is one of the 5 main chemical compounds found and utilised by man. The other chemical compounds being gold, copper, lead and iron. Silver was subsequently discovered after gold and copper. Silver is found naturally as a free metal, but a lot less regularly than gold or copper. More oftentimes, silver and lead are found together in nature. Archaeologists (scientists who study ancient civilizations) have found silver objects dating to about three thousand four hundred BC. In Egypt. Drawings on some of the oldest pyramids show men working with metal, likely extracting silver from its ores. Written records from India describe the silver metal as far back as about nine hundred BC. Silver was in common use in America when Europeans first arrived.

The Bible contains many references to silver. The metal was employed as a method of commerce. There were also many decorated temples, palaces, and other vital buildings. The Bible also contains sections that describe the creation and refinement of silver.

The largest producers of silver in the world are Mexico, Peru, Canada, Poland, Chile, Australia and United States. In the U. S., silver is produced at 76 mines in 16 states. The biggest state producers are Nevada, Idaho, and Arizona. These three states account for approximately two thirds of all the silver mined in the US.

An American exploration company has discovered a large haul of 150 million pounds of silver in the wreck of a British ship that was traveling from Kolkata to London, that was sunk by a German U-boat in the Atlantic in 1941. Marine archaeologists from an exploration company based in Florida found the SS Gairsoppa resting nearly three miles underneath the surface of the ocean with two hundred tons of silver stored in its hold.

Silver has for a while been highly regarded as a precious metal, and it's used to make ornaments, jewellery , high-value tableware, utensils, and obviously, utilized in commerce as coins. Today, silver is also utilized in electric contacts and conductors, in mirrors and in catalysis of chemical reactions. Its compounds are also used in photography , as well as, dilute silver nitrate solutions and other silver compounds are utilised as disinfectants. While many medical anti-microbial uses of silver have been replaced by antibiotics, further research into clinical potential continues. And, according to many different studies, about 13,540 tons silver was used in the electromagnets for enriching uranium during World War Two .
