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 ]
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]
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 ...
In the rocker, along with the gold, was a large quantity of heavy blue-black material almost like putty that clogged the rocker and interfered with the washing out of the fine gold. When assayed on June 27, it was determined to be a rich sulfide of silver; in fact, the ore was three fourths silver to one fourth gold. [2]: 8–9, 11
The main ores mined at Rammelsberg were lead-zinc ore, copper ore, sulphur ore, mixed ore (Melierterz), brown spar (Braunerz), barite ore (Grauerz), banding ore (Banderz) and kniest along with the important minerals of galena, chalcopyrite, sphalerite, baryte and vitriols. The chief metals extracted from these ores included silver, lead, copper ...
Acanthite, monoclinic silver sulfide, one of the most famous silver ore minerals. Argentite, silver sulfide of the orthorhombic system, one of the oldest silver ore minerals. In addition, there are several more mixed minerals, part of the name of which is also silver glance: Antimony-silver glance (German: Antimonsilberglanz) — Stephanite ...

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.
