Proustite is a sulfosalt mineral consisting of silver sulfarsenide, Ag 3 As S 3, known also as ruby blende, light red silver, arsenic-silver blende or ruby silver ore, and an important source of the metal.
Methods for mining silver change for every body of ore. The method that's chosen depends on the grade of the ore, the steepness and shape of the terrain, its depth, host rock, transportation availability, and other economic factors. [7] Commonly, silver ore is obtained from open pit mines, and underground drifts and shafts. [7]
Apparently, Sol mixed the pure silver with other lesser metals to make his money. Solomon never disclosed where he obtained the pure silver, but many people speculated that he found the silver in one of the many caves on Pine Mountain close to his farm. Once, Solomon was caught by a U.S. detective while at work in the cliffs.
Silver occurs in veins filling fracture zones through Paleozoic limestone. Minerals in the silver-ore veins include polybasite, pyrargyrite, proustite, sphalerite, galena, and tennantite. Manganese occurs as replacement bodies of pyrolusite and rhodochrosite in limestone adjacent to the fracture zones. No mines are presently active in the ...
Galena is also an important ore mineral in the silver mining regions of Colorado, Idaho, Utah and Montana. Of the latter, the Coeur d'Alene district of northern Idaho was most prominent. [2] Australia is the world's leading producer of lead as of 2021, most of which is extracted as galena.
The patio process is a process for extracting silver from ore. Smelting, or refining, is most often necessary because silver is only infrequently found as a native element like some metals nobler than the redox couple 2 H + + 2 e − ⇌ H 2 (gold, mercury, ...). Instead, it is made up of a larger ore body.
Pyrargyrite is a sulfosalt mineral consisting of silver sulfantimonite, Ag 3 SbS 3. Known also as dark red silver ore, ruby blende, garnete blende or ruby silver, it is an important source of the metal. It is closely allied to, and isomorphous with, the corresponding sulfarsenide known as proustite or light red silver ore.
From historical records beginning in 1904, the Sunshine Mine has produced 364,893,421 ounces of silver from 12,953,045 tons of ore through 2001, when the mine was closed. From January 1, 1998, to January 1, 2004, the average reserves carried by the mine were 1.38 million tons, containing 32.20 million ounces of silver at 23.3 oz Ag/ton.
