Silver Mining and Refining Education

Modern Silver Mining. Even these ores are found in small quantities, and many tons of material must be mined to produce just a few ounces of silver. At least 80 percent of the world’s silver is produced instead as a by-product of mining for other metals such as gold, copper, lead, zinc, and uranium.

Silver, Chemical Element reaction, water, uses, elements

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.

The Facts on Silver Dartmouth Toxic Metals

Ingesting silver compounds, such as in medicines, can sometimes irritate the stomach. Prolonged exposure to silver dust or to the silver compounds in medicines or supplements can also result in a permanent blue-gray staining of the eyes, nose, mouth, throat and skin. This blue-gray staining is known medically as “argyria.”.
