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]
The upcoming fourth expansion pack for mega-successful MMO World of Warcraft (WoW), Mists of Pandaria, might not be so "hardcore" after all. With a Pokemon-esque pet battling system and now a ...
The Crown Point-Belcher bonanza was discovered in 1870. The ore body extended from the 900 to the 1,500-foot level (275 to 460 m), having a length of 775 feet (236 m) and a width of 120 feet (37 m). The ore, the precious metal value of which was 54 percent from gold and 46 percent from silver, lasted only four years. [2]: 137–138
Galena is the primary ore of lead, and is often mined for its silver content. [6] It is used as a source of lead in ceramic glaze. [27] Galena is a semiconductor with a small band gap of about 0.4 eV, which found use in early wireless communication systems.

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.
Swift's silver mine is an alleged silver mine whose existence is part of the folklore of the Appalachian Mountains. The mine was supposedly discovered in 1760 by an Englishman named Jonathan Swift. [ 1 ]
The government purchases of silver were subsequently nearly doubled by the 1890 Sherman Silver Purchase Act, further extending the boom into the early 1890s. The repeal of the act in 1893 resulted in a collapse of silver prices, bringing about an end to the boom. After 1893, many mining camps became ghost towns. The accompanying collapse in ...
