How is Silver Mined APMEX®

Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.

Silver processing The metal and its alloys Britannica

2020-8-15 · Silver processing Silver processing The metal and its alloys: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.

PROCESS FOR SOLUTION MINING OF SILVER DOW

After leaving the resin, the brine contains mainly (in addition to sodium chloride) silver and copper values. These are precipitated by contacting the brine with hydrogen sulfide. Alternatively, a water-soluble sulfide such as sodium or potassium sulfide can be used. The precipitated copper and silver values are then separated by known techniques.
