These minerals are usually located in the veins of rocks, often alongside other metals like gold, copper, and lead. From Mineral to Metal. While silver does exist in its pure form in nature, it's rare. More often, it's extracted from complex ores that require a detailed process to separate the silver.
Other articles where argentite is discussed: acanthite: 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.
Silver is extracted from the argentite ore by the Mac-Arthur and Forrest's cyanide process. The various steps involved in this process are as follows :a Concentration : The crushed ore is concentrated by froth floatation process.b Treatment of ore with NaCN : The concentrated ore is treated with 0.4 – 0.6% solution of sodium cyanide. This mixture is agitated by a current of air.

How is silver extracted from argentite ore? Hard. View solution > In cyamide extraction process of silver from argentite ore, the oxidising and reducing agents are respectively. Medium. View solution >
Characteristic is the ease with which it is cut. Argentite is stable only above 179 deg C; thus, although few crystals found appear outwardly to be isometric, they are actually composed of acanthite, a chemically identical paramorph belonging to the monoclinic system. Argentite's hardness is 2 - 2.5 and specific gravity is 7.2-7.4.
Argentite, arg, was traditionally presented as a typical silver mineral in the sulfide class, cubic in symmetry and Ag 2 S in composition. However, over time it has been proven that the mineral found in nature is always monoclinic. In reality, it often shows a pseudocubic habit, which had led to its original characterization as cubic.. It is now understood that, in these …
Ores are the minerals from which metals can be easily and economically extracted. Very few metals such as noble metals, i.e., Gold, Silver, Platinum etc. are present in their original metallic forms in nature. Metallurgy is the field of science that deals with the extraction of metals from ores which are naturally found in the environment.
