Telluride minerals such as calaverite, are also important silver ores in some mining districts. This sample of rich gold and silver ore comes from the Cripple Creek district in Colorado. The mossy metallic colored mineral on this specimen is calaverite, a mineral rich in both gold and silver.
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. Deposits of native (chemically free, or uncombined) silver are also commercially important.
Argentite, or silver glance, is the most important and common of silver minerals. What are some important uses of silver? ... Galena is used as the most important ore of lead.
Pure silver is too soft for products like jewelry and tableware, so the family's finest forks and knives are most likely sterling silver, an alloy of 92.5 percent silver and 7.5 percent copper ...
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).
the most important ore of lead is bauxite. Galena, also called lead glance, is the natural mineral form of lead(II) sulfideIt is the most important ore of lead and an important source of silver Galena is one of the most abundant and widely distributed sulfide minerals Live Chat World iron ore reserves by …
Galena is a very important mineral because it serves as an ore for most of the world's lead production. It is also a significant ore of silver. Galena has very few uses beyond its service as an ore, but that should not diminish its importance to society.

Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.
Most of Idaho's placer gold was gone by the time Noah Kellogg (and his burro) found that lump of lead and silver ore in Shoshone County in 1885. This led to more wealth in silver, lead, and zinc than the gold miners could have ever dreamed of finding.
In 1700, New Spain's silver production hovered around 5 million pesos annually. By the 1780s, the figure had quadrupled. As early as 1600, silver ore, bullion, and coins constituted some 80 percent of New Spain's exports, making it far and away the largest and most important industry in Spain's wealthiest and most important colony.
Most true silver deposits, as opposed to argentiferous deposits of other metals, came from Tertiary period vulcanism. The principal sources of silver are the ores of copper, copper-nickel, lead, and lead-zinc obtained from Peru, Bolivia, Mexico, China, Australia, Chile, Poland and Serbia.
The most important use of lead was the extraction of silver. Lead and silver were often found together in the form of galena, an abundant lead ore.The Roman economy was based on silver, as the majority of higher value coins were minted from the precious metal.
Following is a list of minerals that serve as copper ores in the copper mining process:
Today, the most important use of silver is in photography. It is used in electronics, for soldering, and in chemical production. ... Galena is used as the most important ore of lead.
An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element or elements.
Silver can be discovered in ores of horn silver and agentite. It is a precious by-product of dispensation and smelting gold and lead-zinc ores. In 2009, China, Mexico and Chile were ranked the first producers of silver. Its average price in 2009 was $13.40 per ($432 per kilogram), to rose in 2010.
Well, that's obviously because gold and silver are two precious metals. That you already know… But what about other metals? There are other substances equally precious, even more precious than gold, that you must get to know better. So here's a list of the top 10 most precious metals in the world.
Some primary "ore" may contain up to 200 ppm. Ga. Germanium - A byproduct of zinc ore processing. Also a deposit in China is associated with coal. Gold - The primary mineral of gold is the native metal and electrum (a gold-silver alloy). Some tellurides are also important ore minerals such as calaverite, sylvanite, and petzite.
Peru, Australia, and the United States. About 25 percent of the silver mined in the world in 2001 came from silver ores; 15 percent, from gold ores and the remaining 60 percent, from copper, lead, and zinc ores. ... A short list of some of the important uses and the dates

Silver iodide is used in cloud seeding to produce rain. Silver chloride can be made transparent and is also used as a cement for glass. Silver nitrate, or lunar caustic, is used extensively in photography. Although silver itself is not considered toxic, most of its salts are poisonous, due to the anions involved.
Most silver (approximately 80 percent) is extracted as a by-product from complex ores, as well as from gold and copper ores. The extraction of silver from silver and gold ores requires cyanidation—the dissolution of silver in an alkaline solution of sodium cyanide with an inlet for air: 2Ag + 4NaCN + ½O 2 + H 2 O = 2Na[Ag(CN) 2] + 2NaOH
The ore minerals in most of the world's iron and manganese reserves were chemically precipitated in the ocean and accumulated on the sea floor. Placer deposits are heavy metallic minerals, such as iron or titanium minerals, or native gold or diamonds, that have been concentrated by wave or water action in a river or beach environment.
Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS 2. It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years. The surface of chalcopyrite loses its metallic luster and brass-yellow color upon weathering.
