Silver | Geoscience Australia
Silver is present as only about 5 parts in a million (imagine a million smarties and only 5 of them are silver). Unlike most other base and precious metals, silver is mined and produced mainly as a by-product of the mining of other metals - copper, lead, zinc and, to a lesser extent, gold.

Health effects of silver. Soluble silver salts, specially AgNO 3, are lethal in concentrations of up to 2g (0.070 oz). Silver compounds can be slowly absorbed by body tissues, with the consequent bluish or blackish skin pigmentation (argiria). Eye contact: may cause severe corneal injury if liquid comes in contact with the eyes.

The Safe and Effective Use of Cyanide in the Mining Industry
A process called "Cyanide Leaching" or Cyanidation has been the dominant gold extraction technology since the 1970s. Cyanide, in the form of a dilute sodium cyanide solution, is used to dissolve and separate gold from ore [4]. This process was first used in large scale commercial mining in 1889 [3, 4]. Cyanide leaching is safer and more ...

Silver Mining and Refining | Education
Lead ores containing silver are extracted by cupellation, a process developed by the Chaldeans as early as 2,500 B.C. Today, the cupellation process involves heating crushed ore on a porous bed of bone ash until it melts. The lead and other impurities are absorbed into the bone ash, and the molten silver is drawn off.

Silver, Chemical Element
Chemical properties Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound. The tarnish that develops over time on silverware and other silver-plated objects is silver sulfide.
