What rocks are silver found in?
Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching.

What does silver in rock look like?
For ores where the most valuable element is silver, the silver is normally contained in minerals colored gray to black in appearance. These minerals range from a metallic sheen to an earthy soot-like appearance. Sooty black minerals are common in many very rich silver ore samples.
What type of rock has silver flakes?
Re: Which rocks contain metallic flakes resembling silver and gold? The most likely candidate for the silver and gold flakes are iron sulphides – also known as iron pyrites or, "fools gold". Lead sulphide (galena) also produces silvery inclusions that would fit the bill with what you describe.
Where is silver naturally found?
Silver is sometimes encountered in pure form. It also is mined from the minerals acanthite (silver sulfide) and stephanite. Silver also is found in the common minerals chlorargyrite (silver chloride) and polybasite. Silver is mined in many countries, but most comes from the USA, Canada, Mexico, Peru and Bolivia.
Where is silver commonly found in nature?
Silver is found generally in lead ores, copper ores, and cobalt arsenide ores and is also frequently associated with gold in nature. Most silver is derived as a by-product from ores that are mined and processed to obtain these other metals.

Where is silver most commonly found?
Silver can be found across many geographies, but approximately 56% of the world's silver production is found in the Americas, with Mexico, Peru, and Chile supplying 43%. Outside of the Americas, China, Australia, and Russia combine to make up nearly 25% of the world's production.

What does raw pyrite look like?
Identifying Pyrite Hand specimens of pyrite are usually easy to identify. The mineral always has a brass-yellow color, a metallic luster and a high specific gravity. It is harder than other yellow metallic minerals, and its streak is black, usually with a tinge of green.
How do you get silver from a rock?
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.

Gold is also found at times in chalcopyrite, galena and arsenopyrite and stibnite, but not as a rule in such large amounts as may be found in pyrite. Other minerals, like sphalerite, pyrrhotite, magnetite and hematite sometimes carry small amounts of gold as well. Gold also occurs as tellurides such as calaverite.
Does silver stick to a magnet?
"Silver is not noticeably magnetic, and exhibits only weak magnetic effects unlike iron, nickel, cobalt, and the like," says Martin. "If your magnet sticks strongly to the piece, it has a ferromagnetic core and is not silver." Fake silver or silver-plated items are generally made of other metals.
