An ore is an 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 from the earth through mining; they are then refined (often via smelting) to …
Silver as a Native Element Mineral. Silver is rarely found as a native element mineral. When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals.
Silver mining is the resource extraction of silver by mining. for silver and associated minerals (lead, mostly) in the galena ore silver is most commonly found in. Silver Silver mineral information and data.
Silver mining is the resource extraction of silver by mining. Silver is found in native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S ), chlorargyrite ("horn silver," Ag Cl ), and galena (a lead ore often containing significant amounts of silver).
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.
Galena also was a major mineral of the zinc-lead mines of the tri-state district around Joplin in southwestern Missouri and the adjoining areas of Kansas and Oklahoma. Galena is also an important ore mineral in the silver mining regions of Colorado, Idaho, Utah and Montana.
Gold - Mineral Fact Sheets - Australian Mines Atlas. Gold usually occurs in its metallic state, commonly associated with sulphide minerals such as pyrite, but it does not form a separate sulphide mineral itself.

Associated Minerals are silver minerals such as acanthite and prousite, cobaltite, copper, zeolites and quartz. Other Characteristics: ductile, malleable and sectile, meaning it can be pounded into other shapes, stretched into a wire and cut into slices.
Uses: Mineral specimens and as a minor ore of silver. Specimens Dyscrasite is a very interesting, rare and beautiful silver mineral that is popular with collectors who love to collect silver bearing minerals especially micromounted specimens.
Minerals Are Associated With Silver Ore. Ore - Wikipedia. An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit.
Gold and Silver, Rocks and Minerals, Kentucky Geological Survey. Aug 1, 2012 KGS Home > Rocks and Minerals Gold and Silver. Gold and silver are commonly found in areas where igneous and metamorphic activity has occurred and are generally associated with silicic types of intrusives and Precambrian metamorphic rocks.
Minerals Associated or Found in Gold Placer Gold Associated Minerals: Placer gold invariably is accompanied by other heavy minerals, which comprise the black, white, or yellow concentrates found in the sluice box when cleaning up.
silver ore associated with zinc deposit. of the more than known lead containing minerals, by far the most important primary ore of the metal is the lead sulfide galena pbs .galena often contains silver, zinc .
The southwestern Hokkaido mining district is well known for the occurrence of many epithermal ore deposits ofNeogene Tertiary period.The ore mineral assemblages in the epithermal gold-silver deposits from the southwestern Hokkaido such as Kobetsuzawa, Shin Otoyo, Suttsu, Chitose, Teine, Date, Koryu and Toya mines are examined.
can contain anomalous concentrations of gold, silver, and cobalt. Deposits associated with felsic volcanic and sedimentary rocks contain minor to significant concentrations of lead, silver, arsenic, antimony, cadmium, and locally bismuth, tin, and selenium. Ore and gangue mineralogy and zonation The dominant sulfide mineral in most VMS deposits is pyrite, but pyrrhotite is dominant in others ...
Silver has many unique physical properties that give it very special status. Silver is the best conductor of electricity, is the second most malleable and ductile metal, and is in greater abundance than all other precious metals with similar properties.
Mineral deposit - Native metals: Only two metals, gold and platinum, are found principally in their native state, and in both cases the native metals are the primary ore minerals. Silver, copper, iron, osmium, and several other metals also occur in the native state, and a few occurrences are large enough—and sufficiently rich—to be ore ...
Copper - Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper and …

Deposition of ore minerals accompanies stages 2 and 3. Skarn deposits are typically zoned mineralogically with respect to pluton contacts, orig inal lithology of host rocks, and (or) fluid pathways. Later petrogenetic stages may partly or completely obliterate earlier stages of skarn development. Skarn deposits commonly are also associated with many other types of magmatic-hydrothermal ...
Silver is a common constituent of galena deposits, making them an important silver ore as well. Other uses of galena: While galena is primarily important as lead ore, there are a few uses for this mineral …
Silver mining is the resource extraction of silver by mining. for silver and associated minerals (lead, mostly) in the galena ore silver is most commonly found in. Silver: Silver mineral information and data.
Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron.
Tellurides. Among minerals other than sulphides which contain gold, the tellurides are of most importance in metallurgy. Calaverite is a bronze-yellow gold telluride, usually containing a little silver, occurring in Western Australia and in certain mines in California and Colorado.
