Silver processing - Refining, Alloying, Uses: 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 …Web

Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.Web

20% of gold comes from silver and copper mining. 60% of the silver extracted comes from copper, zinc and lead mining. There are strong correlations between silver production and that of copper and zinc, but less between silver and lead, probably because the amounts originating from lead mining are insignificant in the bigger picture.Web
