About this site

Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. As such, most silver produced is refined from sulfide ores such as galena (lead) or chalcopyrite (copper) which contain small amounts of silver. Many of these ores are mined for their value as sulfide ores, and silver is extracted as a valuable by-product, however, some ores are mined explicitly for their silver value. Flotation separation is a key step in this complicated process. Silver mineralizes most commonly as arge

Silver processing - The metal and its alloys | Britannica

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.
