History and Discovery
The discovery was done after the discovery of copper and gold in around 4000BC. At that time, silver was popularly used in making jewelry and also as a means of exchange.
Silver is commonly found in nature in a mixed state along with copper and lead. The Spanish people claim the discovery of silver mines in Mexico, Peru and Bolivia. By the 16th century, the South and Central America became the largest silver producing areas. By 2000 BC, the sterling bearing lead categories were smelted and mined and an impure silver lead alloy was obtained from the lead ores that were smelted. Later, they were refined by using fire and that process was known as cupellation . The ancient silver mines were located in Greece at the Laurium lead silver deposit.
With the advent of time, the Patio process was used for the new world mines recovery. In this process, silver bearing ore was churned and mixed with roasted copper ore, salt and mercury. Therefore, silver was converted to a finely separated state and was finely dissolved by mercury. This was refined repeatedly by the process of cupellation.
In the 19th century, the Cyanidation procedures displaced the Patio process and Thum Balbach and Moebius electro refining procedures were introduced. A huge silver deposit was found in the mid 19th century in Nevada. After that, by the end of the 20th century, the United States emerged as the largest producer of sterling in the world.
