If it turns the correct color then the silver is real

What kind of rock is 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.

How do you test for raw silver?

Just place a drop of bleach on the silver item. If it tarnishes after coming in contact with oxidising chemicals like bleach then it is real silver. Real silver will turn black when exposed to bleach.

What is barite used for?

Barite is the primary ore of barium, which is used to make a wide variety of barium compounds. Some of these are used for x-ray shielding. Barite has the ability to block x-ray and gamma-ray emissions. Barite is used to make high-density concrete to block x-ray emissions in hospitals, power plants, and laboratories.

Where can I find galena?

Galena is found in cavities and brecciated (fractured) zones in limestone and chert, as in the extensive Mississippi River valley deposits, where 90 percent of the U.S. production of lead is mined. The mineral has occasionally been observed as a replacement of organic matter and sometimes occurs in coal beds.

What is argentite mineral?

Argentite is the high-temperature form of acanthite. Like several other sulfides, selenides, and tellurides of silver and copper, argentite forms isometric crystals at high temperatures. Upon cooling these crystals invert from isometric (cubic) to monoclinic structures while remaining unchanged in external appearance.

How do you get silver from argentite?

Argentite is the ore of silver with formula Ag2S. it is extracted by the process commonly known as Mac Arthur and Forrest’s Cyanide process. The ore is firstly crushed. Now the concentration of ore is done by the Froth floatation process.

How is silver extracted from argentite ore?

The argentite ore dissolves in sodium cyanide forming sodium argento cyanide. The reaction is reversible so is passed to oxidize Na2S to Na2SO4 such that the equilibrium shifts towards the product. The solution is filtered and the filtrate containing sodium argento cyanide is used to recover silver metal.

How do you extract silver?

How and where is silver extracted? Silver ore is mined through both open-pit and underground methods. The open pit method involves using heavy machinery to mine deposits relatively near the earth’s surface. In underground mining, deep shafts are dug into the ground to extract ore.
