Silver is sometimes found in nature as a free metal but also appears with other minerals and deposits of ore like copper, gold, nickel, lead and lead-zinc. Silver is heavily mined around the world with the largest deposits being mined in China, Australia, Peru, Poland, Serbia, Bolivia, Mexico and Chile.
Accordingly, what colors do you need to make silver?
If you’re painting a picture with a silver element in it, then black and white in various proportions, as well as tinges of whatever surrounding colors giving off reflected light to silver – mixed into those proportions of black and white.
How do we mine silver?
Mining and concentrating. Silver-bearing ores are mined by open-pit or underground methods and then are crushed and ground. Since virtually all the ores are sulfides, they are amenable to flotation separation, by which a 30- to 40-fold concentration of mineral values is usually achieved.
How do we obtain silver?
Silver can be obtained from pure deposits, from silver ores such as argentite (Ag2S) and horn silver (AgCl), and in conjunction with deposits of ores containing lead, gold or copper. Sterling silver, an alloy containing 92.5% silver, is used to make silverware, jewelry and other decorative items.
Is silver rare?
Most studies agree gold is overall the more rare of the two metals; however, above ground silver is actually more rare than gold. Estimates report gold is 5-7x more abundant above ground than silver. To date, over 1.5 million tonnes of silver have been mined.
How common is silver on earth?
Silver is the 68th most abundant element in the Earth’s crust and 65th in cosmic abundance. It is found in small quantities in many locations on Earth. Its mostly important ores are sulfides, of which argentite (silver sulfide, Ag2S) is the most common.
How did Silver get its name?
Our name for the element is derived from the Anglo-Saxon for silver, ‘seolfor,’ which itself comes from ancient Germanic ‘silabar.’ Silver’s chemical symbol, Ag, is an abbreviation of the Latin word for silver, ‘argentum.’ The Latin word originates from argunas, a Sanskrit word meaning shining.
How is silver formed in the earth?
The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

How is silver extracted and purified?
Silver is extracted from the ore-argentite ((Ag_2S)). The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution. Then the silver obtained is purified by electrolytic process.
How do we use silver?
Uses of Silver in Jewelry and Silverware. Jewelry and silverware are two other traditional uses of silver. Malleability, reflectivity, and luster make silver a beautiful choice. Because it is so soft, silver must be alloyed with base metals, like copper, as in the case of sterling silver (92.5% silver, 7.5% copper).
Why silver is so important?
It has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Silver occurs in pure form, as an alloy with other metals or in minerals. Moreover, silver ions and compound can kill bacteria, algae, and fungi; therefore, silver helps purify, sanitize, and filter water.
Is silver a chemical?
Silver (Ag), chemical element, a white lustrous metal valued for its decorative beauty and electrical conductivity. Silver is located in Group 11 (Ib) and Period 5 of the periodic table, between copper (Period 4) and gold (Period 6), and its physical and chemical properties are intermediate between those two metals.
Is gold or silver more expensive?
One such implication is that the precious metals differ in value. You might ask yourself what makes silver so different from gold, but the truth is, gold is far more valuable than silver. Platinum, likewise, is far more expensive to purchase, in accordance with its high level of scarcity.
Where is silver mined in the world?
Mexico, the world’s biggest silver producing country, and Poland host three each of the world’s ten biggest silver mines. Bolivia, Turkey, Peru and Australia host the remaining four. Mining-technology.com profiles the ten biggest silver mines in the world, based on contained silver reserves.
What was the element silver named after?
Silver was discovered by Known since ancient times in unknown at not known. Origin of name: from the Anglo-Saxon word “siolfur” meaning “silver” (the origin of the symbol Ag comes from the Latin word “argentum” meaning “silver”).
Is silver a reactive?
It is not reactive. It does not dissolve in most acids. Nitric acid dissolves it, though, to make silver nitrate. It does react with strong oxidizing agents like potassium dichromate or potassium permanganate.
Is silver ore?
As silver is a precious metal often used for coins, its mining has historically often been lucrative. As with other precious metals such as gold or platinum, newly discovered deposits of silver ore have sparked silver rushes of miners seeking their fortunes.
What group is silver in?
Group 11 element. Group 11, by modern IUPAC numbering, is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), and gold (Au).
What are the properties of silver?
Of all the metals, silver is the best conductor of heat and electricity known, in fact it has the highest electrical and thermal conductivity known for any material. It is strong, malleable and ductile, and can endure extreme temperature ranges. Silver is also able to reflect light very well.
What is the ore of silver?
Silver ores. The most common silver-bearing minerals recovered by flotation are argentiferous galena, native silver, argentite (Ag2S) and tetrahedrite (Cu,Fe,Ag) Sb4S3). Often these minerals float with the base metals such as copper and lead sulphides or are the primary target mineral (tetrahedrite).
Where platinum can be found?
Used by the pre-Columbian Indians of South America, platinum wasn’t noticed by western scientists until 1735. Platinum can occur free in nature and is sometimes found in deposits of gold-bearing sands, primarily those found in the Ural mountains, Columbia and the western United States.

What states can you find silver in?
Silver mining in the United States
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858.
United States mines produced 1,170 tons of silver in 2014, 17% of the silver it used.
In 2015, Alaska was the nation’s leading silver-producing state.
