[7] Commonly, silver ore is obtained from open pit mines, and underground drifts and shafts. [7]
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
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 ...
